Products Description
ICS TRIPLEX T9451 8-Channel Isolated Digital Output Module in stock
ICS TRIPLEX T9451 is an 8-channel galvanically isolated digital output module for AADvance SIL3 safety instrumented system. It receives safety logic commands from T9110 processor and converts internal signals into 24VDC drive outputs to control field solenoid valves, shutdown valves and alarm devices. It supports dual redundant signal path design for high-reliability safety execution.
This module features continuous per-channel load current and voltage monitoring, wire break and short-circuit fault diagnosis. It mates with T9852 termination assembly for field wiring connection. It meets IEC 61508 SIL3 safety standard. It is discontinued legacy hardware, used for spare replacement and retrofit of existing AADvance safety systems.
