Emerson DeltaV S‑Series SE4003S2B1 (KJ3222X1‑BK1) 8‑Channel 4‑20mA HART Analog Input Module

Description

Emerson DeltaV S‑Series SE4003S2B1 (KJ3222X1‑BK1) 8‑Channel 4‑20mA HART Analog Input Module

Product Details

The SE4003S2B1, alternate part number KJ3222X1‑BK1, is hot‑swap standard I/O module for Emerson DeltaV S‑Series DCS system, non‑CHARM, fits S‑Series carrier such as SE4050E0C0 backplane baseplate. Origin: USA.

8‑channel 4‑20 mA analog input with native HART pass‑through, channel‑to‑channel isolation 1500 VDC. Typical accuracy ±0.1% of reading. Backplane powered 12VDC, field side 24VDC loop supply. Operating temperature ‑40℃ ~ +70℃; conformal coated PCB, ISA‑S71.04‑1985 Class G3 for corrosive cabinet environment. Hot‑swap support, module replacement without system shutdown. Hardware self‑diagnosis for loop open‑circuit, short‑circuit and module fault. CE / ATEX certified, lifecycle active production, available as original new spare‑parts for petrochemical, power plant DCS projects.

Note: For redundant pair configuration, must use identical part number & hardware revision, mixing standard and AI‑plus module will trigger configuration mismatch alarm and lose redundancy function. Matching terminal block: CE4003S2B1.

Applications

‑ Petrochemical & refinery 4‑20mA smart transmitter signal acquisition ‑ Power‑plant boiler/turbine pressure, flow analog signal monitoring ‑ Oil‑gas on‑site and offshore DCS control cabinet ‑ Chemical plant reactor process parameter measurement ‑ Pharmaceutical process automation analog input loop ‑ Retrofit & spare‑part replacement for DeltaV S‑Series DCS system ‑ Harsh corrosive cabinet environment DCS signal collection
