Load Monitoring for 3RF

SIRIUS Load Monitoring for 3RF

This module monitors partial loads (several heating systems on a 1-phase solid state relay/contactor) for failures and also reports tripped fuses and thyristor faults to the controller.

The basic version is capable of monitoring six load elements. The expanded version controls maximum twelve load elements. As well as detecting the current, it also detects the load voltage and reports thyristor and network faults.

Faults are displayed over one or more LEDs and signaled to the controller over a PLC-compatible output.


  • Operation of several heating elements with constant
    resistance at a 1-phase solid-state relay or solid-
    state contactor
