H2-Alarm device
Compatible with the H2-CNI 4-20mA-I and H2-meTCD 4-20mA or H2-CNI 0-10V-I and H2-meTCD 0-10V
The H₂ alarm module reliably monitors multiple hydrogen sensors and provides clear, configurable alarm signaling to ensure early detection and operational safety.
Key Features & Benefits
Multi-Channel Sensor Monitoring
The H₂ alarm module provides reliable monitoring of up to four hydrogen sensors of type H2-CNI 0–10V-I and H2-meTCD 0–10V, making it ideal for safety-critical and industrial applications. Each sensor is powered by an independent supply voltage, ensuring high operational reliability.
The module supports a three-color 24 V LED warning light for clear visual alarm signaling. Factory default thresholds distinguish between normal operation, pre-alarm, and main alarm, allowing early detection of critical hydrogen concentrations. All alarm thresholds can be individually configured via the SensorControl software when connected to a Windows® PC through the Micro-USB interface.
Each sensor’s status is indicated directly on the module by four tri-color LEDs and can additionally be transmitted potential-free via the D-Sub 15 interface to an optional relay card. An automatic switchover between main and auxiliary 24 V power supplies ensures uninterrupted operation in case of power failure.
The robust housing made of anodized aluminum is designed for control cabinet installation and mounts easily on a DIN rail (TH 35). All connectors are located on the front panel, and an illuminated on/off switch provides safe and convenient operation.
