The Emerson KJ3201X1-BA3 is a 32-channel discrete input (DI) module designed for the Emerson DeltaV distributed control system (DCS). It’s part of the Series 2 I/O platform and provides high-density input processing for on/off field devices such as switches, contacts, and discrete sensors. This module captures discrete signals and communicates them reliably back to the DeltaV controller for process monitoring and logic control.
