Emerson CE4003S2B1 (KJ3222X1-BA1) DeltaV S-Series 8-channel HART analog input module, collects 4–20mA signals from smart transmitters, maintenance spare for process DCS automation.

Product Overview

• Part No: CE4003S2B1, KJ3222X1-BA1
• Brand: EMERSON

• Category: 8-Channel HART Analog Input Module CE4003S2B1 (KJ3222X1-BA1) is an S-Series analog input module for Emerson DeltaV distributed control system. It acquires 4–20mA analog signals from field pressure, flow, temperature transmitters and supports HART 7 protocol for bidirectional communication with smart instruments. The module executes high-precision A/D conversion and transmits process variable data to DeltaV controllers for closed-loop control. Independent galvanic isolation is equipped for each channel to suppress electromagnetic interference from field wiring. Hot-swap capability allows online module replacement without interrupting system operation. Front panel LED indicators display module status, communication activity and channel faults to facilitate fast field troubleshooting. It serves as key spare part for maintenance and upgrade of petrochemical, power and water treatment control systems.
