Didactum 4-20mA Connector

The Didactum 4-20mA Connector enables the simple and reliable integration of analog 4-20mA sensors into Didactum IT monitoring systems. This allows central collection, supervision, and documentation of diverse measurements such as temperature, humidity, pressure, fill levels, or industrial process values. For server room monitoring, data center security, or critical infrastructures, this connector provides maximum flexibility and safety.

Easy Installation & Configuration

Commissioning the 4-20mA Connector is straightforward:

• Connection via RJ-11 cable to an analog port (A1–A8) of the Didactum system
• AutoSense: automatic detection in the web interface
• Individual configuration of measurement types, labels, and thresholds
• Real-time alerts via e-mail, SMS, or SNMP trap when thresholds are exceeded

Integration into Critical Infrastructure

The 4-20mA Connector opens up a wide range of use cases beyond standard environmental sensors. Examples include:

• UPS monitoring: supervision of emergency power supply
• Fill level monitoring: tanks, water reservoirs, or industrial fluid systems
• Pressure control: differential pressure sensors in HVAC or clean rooms
• Leakage warning systems: integration of specialized moisture sensors
• Process monitoring: documentation of industrial & production parameters

Scalability & Remote Monitoring

By connecting multiple analog 4-20mA sensors and using Didactum port expansion modules, extensive infrastructures can be monitored. All values are:

• displayed in real time via the web interface
• integrated via SNMP v1/v2c/v3 into monitoring tools such as Nagios, PRTG, Zabbix, or OpenNMS
• archived for long-term analysis (with storage options up to 500 GB)
• shown in centralized dashboards across sites

Typical Use Cases

• Server room monitoring: integration of temperature and humidity sensors
• Data center security: alarms for anomalies in climate data or power supply
• UPS monitoring: supervision of battery voltage and emergency supply systems
• HVAC & building systems: differential pressure or air quality control
• Industrial processes: integration of fill level or process sensors
• Early fire detection: connection of analog smoke or temperature detectors

Benefits for Enterprises

• Flexible integration of 4-20mA sensors into Didactum systems
• Universal applications in IT monitoring, energy management, and industrial processes
• Reliable alerting via e-mail, SMS, or SNMP
• Scalable design for monitoring large infrastructures
• Easy operation via the Didactum web interface
• Audit- & compliance-ready with continuous event logging

Practical Examples

• Data center: integration of differential pressure sensors in cold aisle containment
• Server room: connection of analog smoke and temperature detectors for early fire detection
• Energy plant: monitoring of cooling water levels and pressure sensors
• Industry: comprehensive process monitoring with multiple 4-20mA sensors in series
