Technical Specifications 24VDC control power, multi-channel isolated dry relay contact output. Operating temperature: -40℃ ~ +70℃.
Functional Features Command reception, relay driving, electrical isolation, action status feedback, overload protection.
Application Scenarios Fault alarm output, trip signal forwarding, external cabinet interlock transfer.
Performance Parameters High isolation voltage, reliable pull-in performance, stable repeated action.
Structural Characteristics Rack pluggable module, relay action and fault LED indicators.
Working Principle When receiving output command from the main processor, the internal relay coil is energized, and the isolated dry contact closes or opens to switch external load circuits.
Installation Requirements Field load wiring must match the rated voltage and current of relay contacts, separate control cable and load cable.
Usage Notes Do not exceed contact rated capacity, check contact ablation condition periodically.
