Didactum DC Current Transducer Probe
€119.00
Precise Probe for DC Current Measurement
The Didactum DC current transformer probe is a simple, open-loop Hall-effect DC current transducer that measures direct current on a cable contactlessly, without interrupting it. The cable to be measured is routed through the opening of the ring-shaped transducer; the probe converts the measured DC current into a proportional 0–5V DC output signal.
This article refers to the DC-100 model with a rated current of 100A and a measurement range of 0–100 A — ideal for monitoring battery systems, DC busbars, and DC distribution lines.
Important note: The Didactum DC current transformer probe measures the current on the cable, but cannot transmit the measured signal to a monitoring system on its own. The Didactum current transducer in the DC version, item no. DI14030-DC, is additionally required as a transceiver. It receives the probe’s 0–5V signal and forwards it via an analog port (A1…A8) to the Didactum monitoring system. Without the DI14030-DC, no display, evaluation, or alarm notification of the measured values is possible.
Design of the Current Measuring Probe
The current measuring probe consists of a ring-shaped transducer head with a pass-through opening and a 4-pin terminal block.
Pass-through opening (Ø 21 mm)
The DC cable to be measured is routed through this opening in the ring-shaped toroidal transducer core. The probe measures the current contactlessly via the magnetic field generated.
Mounting tabs
Two mounting tabs on the housing used to secure the probe with screws and nuts.
4-pin terminal block (3.81 mm pitch)
Four-wire terminal for connection to the Didactum current transducer DI14030-DC. Pin assignment: G (Ground), M (0–5V measurement signal), G (Ground), + (+12V DC supply).
Mounting and Connection
The current measuring probe and the Didactum current transducer (DI14030-DC) are installed together.
Mount the probe
Secure the current measuring probe in a suitable location using screws and nuts. Route the DC cable to be measured through the probe’s pass-through opening.
Wiring to current transducer DI14030-DC
Connect the 4 wires of the terminal block (G, M, G, +) to the 3-pin input terminal of the Didactum current transducer (DI14030-DC, DC version) according to the pin assignment.
Connect to the monitoring system
Connect the Didactum current transducer (DI14030-DC) via RJ11 cable to a free analog port (A1…A8) of the Didactum monitoring system or an 8-port sensor expansion unit.
Safety instructions: Comply with the applicable regulations for installation in the respective country as well as the relevant accident prevention regulations, and also with internal operating, work, and safety rules. The specified technical limits, in particular insulation voltage, pass-through diameter, and ambient temperature range, must under no circumstances be exceeded. Before installation, check the maximum permissible cable diameter and the maximum insulation voltage of the probe.
Full Control over Thresholds, Trends, and Automation
Via the Didactum current transducer (DI14030-DC), the probe integrates seamlessly into the Didactum web interface.
- Individual thresholds (Lower Critical, Lower Warning, Normal, Upper Warning, Upper Critical) for each measuring point
- Logic schemes for automated actions when limits are exceeded, e.g. in case of overload or deep discharge
- Clear, individually configurable dashboard
- Graphical trend display and continuous logging of measured values
- Notifications by email, SMS, SNMP trap, and additional channels
Use Cases for the Current Measuring Probe
- Monitoring load current on DC Hall probes for battery strings, DC busbars, and distribution lines for remote power consumption monitoring
- Detecting overload and assessing the condition of DC circuits
- Monitoring charging and discharging currents in battery banks, UPS systems, and energy storage systems

Frequently Asked Questions
What current range is this model suitable for?
This model (DC-100) has a rated current of 100A and covers a measurement range of 0–100 A. Make sure the maximum expected operating current of the monitored cable stays safely within this range.
Can the current measuring probe be connected directly to the monitoring system?
No. The probe provides a 0–5V analog signal and requires the Didactum current transducer in the DC version (DI14030-DC) as a transceiver to transmit this signal to an analog port of the monitoring system.
Is DI14030-DC included in the package?
No. The Didactum current transducer DI14030-DC is a separate product and must be ordered additionally unless already available.
Does the cable need to be cut for installation?
No. The current measuring probe measures contactlessly through the magnetic field of the cable routed through the pass-through opening. Cutting the cable is not required for measurement.
Can multiple current measuring probes be used at the same time?
Yes. Each DC circuit to be monitored requires its own DC-100 current measuring probe with its own Didactum current transducer (DI14030-DC) on a free analog port. If the available ports are not sufficient, the number can be increased using an 8-port sensor expansion unit.
Is the probe also suitable for AC measurements?
No. The Didactum DC current transformer probe is designed exclusively for direct current (DC). For AC measurements, a separate product is available that is combined with the AC version of the Didactum current transducer.
