Key Features
Safety Loop Monitoring: Each input has loop monitoring, capable of detecting on-site line open circuit / short circuit, suitable for safety-critical circuits.
Latching Function: Key channels can latch pulse signals (such as valve action), requiring manual / logical reset, facilitating accident traceability.
High Integrity Design: Dual voltage compatibility (5/24VDC), optically isolated, strong anti-interference, suitable for high-risk scenarios such as chemical and power industries.
System Integration: Communicates with FSC controller through fault-tolerant backplane bus, supports real-time safety logic processing.
Typical applications:
Petrochemical industry: Emergency shutdown (ESD) system of SIS, flame/gas detection signal acquisition.
Power industry: Safety monitoring of power plant boilers / steam turbines, interlock protection of substations.
Process industry: Switch quantity monitoring of water treatment, pharmaceuticals, metallurgy, etc. for safety instrument systems.
