1.Module Role
7400209-030 is the 32-point digital output base for Tricon TMR.
Works with DO3401 output card to deliver SIL 3 “last-mile” driving.
Each channel is galvanically isolated and protected against over-current, short-circuit and ground fault.
Can drive solenoids, relays and sounders directly.
