3. Working Principle
- Power-on Initialization & Self-test: After 24V DC power-on, the module completes full self-inspection of hardware, channels, bus and power loop, loads preset logic parameters, and enters standby monitoring state.
- Bus Command Reception & Parsing: It receives switch control commands from the DCS main controller via high-speed backplane bus, verifies and decodes signals, and eliminates interference mis-commands to ensure logic accuracy.
- Contactless High-speed Switching: Adopting electronic contactless switching technology, each channel independently turns on or off rapidly without mechanical wear or signal bounce, realizing high-frequency and high-precision switch control.
- Field Load Drive Output: The conducting channel outputs stable drive signals to control on-site solenoid valves, contactors, indicators and interlock loops, realizing automatic process start-stop and logic switching functions.
- Real-time Status Monitoring & Feedback: The module continuously monitors channel load status and loop conditions, and uploads operating data and fault information to the upper DCS system for remote visual monitoring.
- Fault Locking & Fault Tolerance: Once detecting short circuit, open circuit or overload faults, the faulty channel is locked and alarmed immediately. Single-channel failure does not affect other channels, ensuring system fault-tolerant and continuous operation.
