Technical Specifications 24VDC power supply, multi-channel discrete input and relay output. Operating temperature: -40℃ ~ +70℃, input debounce circuit built in.
Functional Features Switch status detection, signal debounce, relay output drive, open-circuit fault alarm, interlock signal transmission.
Application Scenarios Prime mover safety interlock circuits, alarm output cabinets, engine auxiliary switch signal collection.
Performance Parameters Fast signal response, reliable contact drive, strong anti-surge capability.
Structural Characteristics Rack pluggable PCB module, LED indicators for each input and output channel.
Working Principle The module scans all discrete input points continuously to identify switch states, sends status data to the main controller, and executes relay actions once it receives output commands.
Installation Requirements Install on designated rack slots, use separate wiring trays for digital signals and power cables.
Usage Notes Do not exceed rated load of relay contacts, verify all interlock logic after replacement.
