Monitoring System 300T

Didactum Monitoring System 300 – High-End Rack and Infrastructure Monitoring

The Didactum Monitoring System 300 is an advanced monitoring and control unit specifically designed for DIN rail mounting in industrial environments, server and industrial racks, and complex electrical systems. With this system, operational and environmental parameters can be reliably monitored and controlled to ensure optimal functionality and safety of critical infrastructures. Combining IP-based monitoring, extensive sensor integration, and intelligent automation, this system is an indispensable solution for companies requiring continuous uptime and security of their IT and production infrastructure.

The Monitoring System 300 precisely measures parameters such as temperature, humidity, voltage, power supply, airflow, smoke, water ingress, vibration, and the status of doors or server cabinets. Through its intelligent sensor ports, CAN bus interface, and optional expansions, up to 1000 physical and logical elements can be monitored in real time. All data is securely stored in the internal memory and can be used for evaluation, reporting, or compliance documentation.

By integrating I/O DIN control, devices such as fans, generators, UPS systems, circuit breakers, alarm systems, and door controls can be centrally managed. Using the intuitive web interface, administrators can view all sensor data, define trigger and alarm logic, activate relays, and adjust response plans in real time. Thus, the Didactum Monitoring System 300 combines monitoring, automation, alarm management, and data acquisition in one unified platform.

Technical Features and Interfaces

The system features four analog sensor ports, one CAN bus port for digital multi-sensors, an Ethernet port, a micro-USB port, and an SD card slot for local data storage. Eight potential-free inputs and five potential-free outputs enable integration of external alarm or control devices. Two relays (12 V DC, 0.25 A switching capacity) can be used for sirens, strobe lights, fan control, or building systems. Optionally, an LTE modem can be installed to provide redundant Internet connectivity for remote monitoring.

All common Didactum sensors are supported, including:

• Temperature and humidity sensors
• Smoke detectors
• Water sensors and leak detection cables
• Vibration sensors
• Magnetic contact and door sensors
• Power and voltage sensors
• Multi-sensors (combined temperature, humidity, smoke)

With support for Modbus TCP/IP, SNMP v1/v2c/v3, HTTP, HTTPS, FTP, Syslog, and other protocols, seamless integration into existing monitoring and building automation systems is ensured. Expansions such as the Modbus RTU module allow integration of up to 32 additional measurement devices and sensors. This flexibility makes the system ready for future requirements.

Practical Examples of Sensor Interaction

The true strength of the Monitoring System 300 lies in the intelligent automation and interaction of connected sensors. Examples from practical use include:

• Temperature monitoring in the server room: When the threshold of 30 °C is exceeded, the system automatically activates air conditioning units, sends alerts via email and SMS, and logs measurements. Simultaneously, a siren can be triggered. Combined with a door sensor, alerts can be suppressed when manual intervention is already in progress.
• Water sensor under raised floor: Upon detecting water leakage, the system instantly sends notifications to IT and facility managers. At the same time, pumps can be activated or valves closed via relay control to prevent further damage. Data is archived and exported as a CSV file for maintenance records or insurance documentation.
• Smoke detector in production hall: If smoke is detected, the system automatically triggers alarms and strobe lights, notifies security staff via e-mail and SMS, and can activate the fire alarm system. Escalation plans such as shutting down machinery or ventilation can be configured via the web interface.
• Vibration sensor on servers or industrial machinery: Unusual vibrations are immediately detected and logged. Critical occurrences trigger email/SMS alerts and can shut down fans or machinery via relays to avoid damage. Alarm chains can involve door sensors to identify possible tampering attempts.
• Magnetic contact and door sensors: Unauthorized access to server racks or doors is logged, and—if integrated with cameras—the system can automatically capture images or video and forward them to the security team.
• Voltage and current sensors: Network voltage and UPS systems are continuously monitored. Power failures or voltage spikes trigger alarms, activate redundant systems, and alert maintenance personnel.

Real-Time Monitoring and Remote Access

Through the web interface, all sensors, relays, inputs, and outputs can be monitored in real time. Administrators can configure individual logic triggers such as:

• Automatic fan control in case of overheating
• Siren and strobe activation when leakage is detected
• Smoke detection alerts via email and SMS
• Logging of access and door opening events in critical racks

For multi-site applications, multiple Monitoring System 300 units can be centrally supervised. Expansion units make it possible to manage hundreds of sensors, ideal for large data centers, factory buildings, or building management systems.

Web-Based Control and Intelligent Automation

The system supports complex logic combinations: for example, if temperature rises in a server rack while a vibration sensor triggers simultaneously, the system can automatically adjust cooling, activate alarms, and send email/SMS notifications to IT staff. All measurements are logged and archived for compliance reporting.

• Door opening during restricted access: video recording starts automatically, relays activate alarm or door locks, notifications are sent.
• Leak under raised floor: valves close automatically, pumps start, alerts are sent to IT and facility management, data exported for insurance.
• UPS failure: audible alarm, notification to administrators, redundant power activated, event logged.
• Smoke detection: alarm activation, optional fire suppression system engagement, warning lights, notification to the security control center.

Data Logging, Analysis, and Reporting

All measurement data is recorded in the internal memory. Graphs for temperature, humidity, water level, voltage, or access status can be displayed via the web interface. Exports in CSV or XML format allow further analysis in tools such as Excel, Cacti, or Grafana. This ensures compliance validation, preventive maintenance planning, and trend analysis for optimizing IT or industrial operations.

Scalability and Expansion Options

The system can be expanded with additional sensor modules, CAN bus extensions, and Modbus RTU devices. Each expansion supports up to eight analog sensors. The CAN bus allows digital multi-sensors and expansions to be installed up to 230 meters away. This flexibility supports installation across large facilities or complex building infrastructures.

In addition, there are two relay outputs and eight potential-free inputs available for sirens, strobe lights, fan control, generators, or building automation. The optional LTE module allows alarm transmission even in the event of IP network failure.

Optional Video Monitoring

USB or IP cameras can be connected via the micro-USB port. When a sensor alarm occurs, images or video clips can automatically be stored or emailed to IT and security personnel. The web interface supports up to four cameras displayed simultaneously.
