Product Details
Description
The DO890 3BSC690074R1 is a 4-channel intrinsically safe output module for hazardous environments, delivering energy-limited power to actuators. Each channel monitors for open- and short-circuit faults, mounts on an extended MTU like the TU890, connects via ModuleBus, and supports hot-swapping for maintenance without interrupting safety or process operation.
