Technical Specifications 24VDC control power; multi-channel relay dry contact outputs; surge suppression circuit; operating temperature -40℃ ~ +70℃.
Functional Features Galvanic isolated switching output; alarm signal transmission; protection trip contact drive; relay channel status monitoring.
Application Scenarios Turbine, gas engine and genset safety interlock and alarm circuits.
Performance Parameters Stable relay contact switching action, high isolation voltage, reliable contact life under rated load.
Structural Characteristics Rack pluggable printed circuit board, onboard relay group and wiring terminal block.
Working Principle Receive digital command signals from main controller. When command is triggered, the internal relay coil is energized or de-energized to change contact status and output switching signal to field interlock equipment.
Installation Requirements Separate weak control wiring and high-power load wiring to avoid electromagnetic interference.
Usage Notes Do not exceed rated voltage and current load of relay contacts; inspect contact aging condition during overhaul.
