Technical Specifications 24VDC power supply, multi-channel dry contact discrete input. Operating temperature: -40℃ ~ +70℃, built-in contact debounce circuit.
Functional Features Switch state scanning, signal debounce filtering, open-circuit fault detection, status data uploading.
Application Scenarios Prime mover safety interlock circuits, start-stop sequence signal collection, auxiliary equipment status feedback.
Performance Parameters Fast state response, stable contact identification, surge suppression for input channels.
Structural Characteristics Pluggable PCB module, LED indicator for every digital input channel.
Working Principle The module scans all input points periodically, filters jitter caused by mechanical contact bounce, and sends confirmed switch state information to the main control unit.
Installation Requirements Install in designated rack slots, separate discrete signal wiring from high-voltage power wiring.
Usage Notes Verify interlock logic after module replacement, strictly prevent high voltage from entering digital input channels.
