3. Working Principle

Standby Initialization: After 24V DC power-on, the coil remains de-energized and all contacts stay open, entering a safe standby state waiting for control commands from the upper PLC/DCS system.
Control Signal Reception: The module receives NPN/PNP differential control signals, energizing the coil and generating electromagnetic suction to drive the internal mechanical structure.
Contact Closing & Conduction: Driven by electromagnetic force, the normally open contacts close rapidly, connecting the rear load and interlock loops to realize indirect control of high-power equipment via weak current signals.
Stable Operation & Loop Monitoring: The contacts maintain stable conduction to ensure normal load operation. The built-in line detection mechanism monitors loop status and line abnormalities in real time.
De-energization & Reset: When the control signal is cancelled, the coil de-energizes, electromagnetic suction disappears, and the internal spring resets to break the contacts and cut off the load loop.
Fault Self-inspection & Fault Tolerance: Real-time monitoring of module operating status and loop conditions. It locks the working state and uploads alarms upon abnormalities to avoid equipment faults caused by mis-switching and ensure control logic safety.
