Emerson DeltaV KJ3222X1-BA1 Series 2 HART Analog Input Module

Emerson DeltaV KJ3222X1-BA1 8-Channel 4-20mA HART Analog Input Card

The KJ3222X1-BA1 (P/N: 12P2532X092) is a high-performance Analog Input (AI) module specifically engineered for the Emerson DeltaV Series 2 I/O subsystem. This module provides eight channels of high-accuracy signal acquisition, designed to interface with 4-20 mA field transmitters. A critical feature of the KJ3222X1-BA1 is its integrated HART (Highway Addressable Remote Transducer) support, which enables the DeltaV system to communicate with "smart" field devices for advanced diagnostics, configuration, and secondary process variables without additional hardware.

Detailed Technical Specifications

The technical data provided below corrects common misinformation regarding this module's channel count and signal type. The KJ3222X1-BA1 (P/N: 12P2532X092) is an 8-channel analog card, not a 16-channel digital card.
