Technical Specifications 24VDC power supply, multi-channel dry contact discrete input. Operating temperature: -40℃ ~ +70℃, built-in signal debounce circuit.
Functional Features Switch status scanning, signal debounce filtering, open circuit fault detection, status data upload.
Application Scenarios Prime mover safety interlock circuits, engine auxiliary switch signal collection, turbine sequence control systems.
Performance Parameters Fast status response, anti-jitter filtering, reliable contact identification, surge protection.
Structural Characteristics Pluggable PCB module, LED indicator for every digital input channel.
Working Principle The module periodically scans all input channels, eliminates false triggering caused by contact bounce through debounce processing, and transmits confirmed switch state to the main control unit for interlock judgment.
Installation Requirements Mount on designated rack slots, separate discrete signal wiring from high-power cables.
Usage Notes Verify all switch definition and interlock logic after module replacement, prevent high voltage access.
