Technical Specifications 24VDC control power, multi-channel isolated dry relay contact output. Operating temperature: -40℃ ~ +70℃, each contact with fixed rated load capacity.
Functional Features Command reception, relay driving, electrical isolation between control and load side, action status feedback, overload protection.
Application Scenarios Generator fault alarm output, safety interlock signal transfer, external cabinet signal forwarding.
Performance Parameters High isolation voltage, reliable relay pull-in, stable repeated action.
Structural Characteristics Rack pluggable module, relay action and fault LED indicators, isolation design between channels.
Working Principle When the module receives an output command, it energizes the internal relay coil. The isolated dry contact closes or opens to switch the external load circuit without direct electrical connection between control side and field side.
Installation Requirements Field load wiring must match relay contact rating, separate control cable and load cable.
Usage Notes Do not exceed rated voltage and current of relay contacts, check contact ablation condition periodically.
