Core Functions
16-Channel High-Speed Digital Acquisition: Acquires 24V DC switching signals with a response time of
Group Isolation and Interference Suppression: 2 groups × 8 channels are grouped and isolated to reduce signal crosstalk and common-mode interference, ensuring signal reliability in complex industrial electromagnetic environments.
Wire Disconnection Diagnosis and Data Integrity: Real-time monitoring of channel wire disconnections and wiring faults; disconnected channels are marked as "invalid" by the PV flag, preventing interlock malfunctions and supporting SIL2 safety requirements.
Redundancy and High Availability: Seamless fault switching during redundant deployment; hot-swappable online replacement ensures continuous operation of critical circuits, suitable for Class I and Div. 2 hazardous areas.
Flexible Power Supply and Safety: Supports internal/external field power selection, providing intrinsically safe field power supply with overvoltage/surge protection, and adaptable to dry/wet contact inputs.
Functions, Applications, and Typical Scenarios
Petrochemical Safety Interlocks: Collects data on ESD emergency stop buttons, combustible gas detectors, and safety valve status to trigger emergency shutdowns and diagnose line breaks to prevent interlock failures.
Power Energy Equipment Monitoring: Monitors motor start/stop, circuit breaker positions, and pump unit operating status, providing real-time data to the DCS to support unit start/stop and fault alarms.
Fine Chemical Process Linkage: Collects valve open/close feedback, agitator operation signals, and level switch status, working with analog output modules to achieve closed-loop control and status linkage.
Metallurgy and Water Treatment: Adapts to multi-area signal acquisition, monitoring limit/operation signals of fans, pumps, and valves to improve system anti-interference and availability.
Smart Factory Data Acquisition: Interacts with MES/SCADA systems to provide equipment status and interlock event data, supporting production traceability and preventative maintenance.
