The Powerful Control Center for IT and Building Infrastructure
The Didactum Monitoring System 100T is the next step up in the Didactum Monitoring family, designed for server rooms, data centers, production facilities, and branch locations that need more powerful yet flexibly expandable monitoring. As an IP-based, self-contained device, it continuously records critical environmental parameters – from temperature and humidity to smoke, water intrusion, and vibration, through to voltage, power outages, and unauthorized access – and raises alerts in real time, before they turn into costly downtime or data loss.
New: the Monitoring System 100T now features Gigabit Ethernet (10/100/1000 Mbit/s), making it ideally suited for use in modern, high-performance network environments. Configuration is done entirely through the web browser, sensors are automatically detected via AutoSense, and the device integrates seamlessly into existing monitoring landscapes such as Zabbix, PRTG, or Nagios via SNMP, Syslog, Modbus TCP/IP, or a REST API.
With up to 100 sensors, 800 freely configurable system elements, and a CAN bus for expansion units, the 100T grows with increasing requirements – from a single server room to a distributed data center site. Optionally, an expansion module (OSDPv2 reader or Modbus/RTU) as well as an LTE modem for independent remote monitoring can be retrofitted.

Analogue sensors
Current Measurement via Hall Effect Current Transformer Directly in the Monitoring System The Didactum current transformer transmits the current values measured by a Hall effect current transformer to a Didactum monitoring system. This analog plug-and-play converter is connected to any analog port (A1 to A8) of a Didactum monitoring system or expansion unit and works with Hall effect current transformers with a 0–5V output signal and 12V DC power supply. This article describes both available variants of the current transformer together: the AC variant for AC measurements and the DC variant for DC measurements. Both variants are identical in design, connection, and functionality, but differ in the type of external Hall effect current transformer they work with. The choice between AC and DC is made directly during the ordering process via the variant selection on this product page. Configuration Individually configurable: AC or DC The Didactum current transformer is already tailored during the ordering process to match the type of Hall effect current transformer already in use or planned. ⚠️ Please note: The correct variant must be actively selected above the shopping cart button under “Select variant”. The AC variant works only together with an AC Hall effect current transformer, while the DC variant works only together with a DC Hall effect current transformer. An incorrect combination will not provide correct measurement values. Select variant AC For monitoring AC current meters. Suitable for use with AC Hall effect current transformers for measuring alternating current. DC For monitoring DC current meters. Suitable for use with DC Hall effect current transformers for measuring direct current. Both variants are identical in connection, structure, and function; details can be found in the “Structure” section below. Structure Current transformer connections The current transformer has only a few, clearly separated connections for input, output, and the external current transformer. 1 Input: 3-pin terminal block 2.54 mm pitch. The external Hall effect current transformer is connected here using 3 wires (0–5V signal and 12V DC power supply). 2 Output: RJ11 6P4C Connects the current transformer via RJ11 cable to an analog port (A1 to A8) of the Didactum monitoring system or a VT408 expansion unit. The 12V DC power supply for the external Hall effect current transformer is provided by the Didactum monitoring system via the analog port and passed through by the current transformer to the current transformer sensor. A separate power supply for the current transformer sensor is not required. Required components Matching Hall effect current transformer required The Didactum current transformer cannot be operated on its own. It absolutely requires an external Hall effect current transformer with 0–5V output and 12V DC supply, which performs the actual current measurement on the line. HALL AC current transformer Open AC current transformer for alternating current, available for measurement ranges from 5 to 50 A. AC current transformer AC current transformer for higher alternating currents, available for measurement ranges from 50 to 500 A. DC current transformer DC current transformer for direct current, available for measurement ranges from 50 to 500 A. Alternatively, any other commercially available Hall effect current transformer with a suitable 0–5V output signal and 12V DC supply can also be used. Installation Install current transformer and sensor together The current transformer sensor and Didactum current transformer are installed together. 1 Mount the current transformer sensor Secure the Hall effect current transformer with screws and nuts. The line to be measured is guided through the aperture of the current transformer. 2 Connect to the monitoring system Connect one end of the RJ11 cable to a free analog port (A1 to A8) of the Didactum monitoring system and the other end to the RJ11 port of the current transformer. 3 Wire the current transformer sensor Connect the 3 wires to the Hall effect current transformer according to the wiring diagram using the 3-pin terminal block of the current transformer. ⚠️ Safety instructions: Observe the applicable regulations for installation in the respective country as well as the relevant accident prevention regulations, in addition to internal company work, operating, and safety rules. The specified technical limits, especially the permissible ambient temperature range, must not be exceeded under any circumstances. Also check the maximum insulation voltage of the current transformer sensor and the maximum permissible cable diameter of the line to be measured before installation.

Compact Hall Effect Probe for Smaller AC Circuits The Didactum Small AC Current Transformer probe is a simple open-loop Hall effect AC current transducer (open-loop ammeter) in a particularly compact design that measures current on a conductor contactlessly without disconnecting it. The cable to be measured is passed through the opening of the ring-shaped transducer; the probe converts the measured AC current into a proportional 0–5 V DC output signal. This article refers to the AC-50 model with a rated current of 50 A and a measuring range of 0–50 A — ideal for individual circuits, outgoing feeders, and smaller to medium-sized loads. ⚠️ Important note: The Didactum Small AC Current Transformer probe measures the current on the conductor, but it cannot transmit the measurement signal to a monitoring system on its own. You also need the Didactum AC Current Transformer, part no. DI14030-AC, which acts as a transceiver, receives the probe’s 0–5 V signal, and forwards it via an analog port (A1…A8) to the Didactum monitoring system. Without the DI14030-AC, no display, analysis, or alarm notification of the measured values is possible. Design Current Probe Design The current probe consists of a compact ring-shaped transducer head with a pass-through opening and a 3-pin connection terminal. 1 Pass-through opening The cable to be measured is routed through the opening in the ring-shaped compact transducer core. The probe measures the current contactlessly via the magnetic field that is generated. 2 Mounting tabs Two mounting tabs on the housing used to secure the probe with screws and nuts. 3 3-pin connection terminal (pitch 3.81 mm) Three-pin terminal for wiring to the Didactum AC Current Transformer DI14030-AC. Pin assignment: + (+12 V DC supply), G (Ground), M (0–5 V measurement signal). ℹ️ Note on confusion: The AC-50 probe has a 3-pin terminal (+, G, M). The larger K6A model for higher currents uses a 4-pin terminal (G, M, G, +). When connecting, make sure the wires are assigned correctly according to the terminal labeling. Installation Mounting and Connection The current probe and the Didactum AC Current Transformer (DI14030-AC) are installed together. 1 Mount the probe Secure the current probe in a suitable location with screws and nuts. Route the cable to be measured through the probe’s pass-through opening. 2 Wiring to current transformer DI14030-AC Connect the 3 wires of the terminal (+, G, M) to the 3-pin input terminal of the Didactum AC Current Transformer (DI14030-AC) according to the wiring assignment. 3 Connect to the monitoring system Connect the Didactum AC Current Transformer (DI14030-AC) to a free analog port (A1…A8) of the Didactum monitoring system or an 8-port sensor expansion unit using an RJ11 cable. ⚠️ Safety instructions: The regulations applicable to installation in the respective country and the relevant accident prevention regulations must be observed, as well as internal company work, operating, and safety regulations. The specified technical limits, especially insulation voltage and ambient temperature range, must under no circumstances be exceeded. Before installation, check the maximum permissible conductor diameter and the maximum insulation voltage of the probe.

Wide operating rangeDesigned for ambient temperatures from -10 °C to +70 °C. Made in EUDeveloped and manufactured in the European Union. FAQ Frequently Asked Questions For which current range is this model suitable? This model (AC-50) has a rated current of 50 A and covers a measuring range of 0–60 Aac. Make sure the maximum expected operating current of the conductor being monitored stays safely within this range. How does this probe differ from the larger K6A probe? The AC-50 probe is more compact and uses a 3-pin terminal (+, G, M), while the K6A probe for higher currents uses a 4-pin terminal (G, M, G, +). Both probes require the Didactum current transformer (AC version) as the transceiver to the monitoring system. Can the current probe be connected directly to the monitoring system? No. The probe outputs a 0–5 V analog signal and absolutely requires the Didactum AC Current Transformer (DI14030-AC) as a transceiver, which transfers this signal to an analog port of the monitoring system. Is the DI14030-AC included in the scope of delivery? No. The Didactum AC Current Transformer DI14030-AC is a separate product and must be ordered additionally if not already available. Does the conductor have to be cut open for installation? No. The current probe measures contactlessly via the magnetic field of the conductor routed through the pass-through opening. Cutting the conductor is not necessary for the measurement itself. Can multiple current probes be used at the same time? Yes. Each circuit to be monitored requires its own AC-50 current probe with its own Didactum AC Current Transformer (DI14030-AC) connected to a free analog port. If the available ports are not sufficient, the number can be expanded using a VT408 expansion unit. Questions about the Didactum Small AC Current Transformer probe?

Precise Hall-Effect Current Transformer for AC Measurement The Didactum AC current transformer is a simple, open-loop Hall-effect AC current transformer (open-loop ammeter) that measures current on a conductor contactlessly without disconnecting it. The conductor to be measured is passed through the opening of the ring-shaped transformer; the transformer converts the measured AC current into a proportional 0–5V DC output signal. This article refers to model AC-100 with a rated current of 100A and a measuring range of 0–100 A — ideal for monitoring individual circuits, feeders, and medium loads. ⚠️ Important note: Although the Didactum AC current transformer measures the current on the conductor, it cannot transmit the measuring signal to a monitoring system on its own. The Didactum current transformer in the AC version, item no.
