The Emerson SE4003S2B5 (KJ3222X1-BK1) is a DeltaV S-Series / Series 2 high-density analog input module assembly designed for mission-critical process signal acquisition in distributed control system (DCS) environments. It combines Emerson’s DeltaV analog input card architecture with a mass termination solution, enabling compact, high-channel-density wiring for large-scale industrial automation systems.
This module is widely recognized as a factory-matched pairing where SE4003S2B5 defines the I/O termination configuration (24-pin mass termination), while KJ3222X1-BK1 is the DeltaV card hardware identifier used in Emerson cataloging and cross-referencing. Together, they form a complete 8-channel 4–20 mA HART-enabled analog input solution for process industries.
It is commonly deployed in environments requiring stable signal acquisition, advanced field diagnostics, and efficient cabinet wiring—especially in oil & gas, petrochemical, and power generation systems.
