Technical Specifications 24VDC power supply, multi-channel dry contact discrete input. Operating temperature: -40℃ ~ +70℃. Each channel has independent surge protection.
Functional Features Switch status detection, signal debounce, open circuit fault diagnosis, status signal upload, interlock trigger signal transmission.
Application Scenarios Turbine auxiliary control system, diesel generator safety interlock cabinet, industrial prime mover protection system.
Performance Parameters Fast response speed, high anti-surge capability, stable switch status identification, long service life.
Structural Characteristics Pluggable PCB module, channel status indicator lights, gold-plated connectors to prevent poor contact.
Working Principle The module continuously detects the on-off state of each external switch, eliminates false triggering caused by signal jitter through internal debounce processing, and sends the confirmed switch state information to the main controller.
Installation Requirements Install on the designated rack, separate switch signal wiring from power wiring, and ensure good grounding.
Usage Notes Check the definition of each input channel before power-on, avoid connecting high voltage to the discrete input channel.
