EMERSON KJ3203X1-BA2 (13P0085X022, VE4001S2T2B4) is a 32-channel 24VDC dry contact discrete input module for Emerson DeltaV DCS system, used to collect passive switch signals and digital status from field devices, with group isolation and built-in fault diagnosis.

Product Overview

EMERSON KJ3203X1-BA2 is a standard S-series I/O board of Emerson DeltaV distributed control system, with part number 13P0085X022 and model code VE4001S2T2B4. It is a 32-channel digital input card designed for acquiring 24VDC dry/wet contact switch signals from field instruments, valves, limit switches and relay contacts. The module transmits collected discrete status data to DeltaV controller through the local I/O bus, supports configurable input filter for contact bounce suppression. It adopts group photoelectric isolation design, effectively reduces field interference, widely used in petrochemical, power, pharmaceutical process control systems.
