Emerson 12P2532X092 KJ3222X1-BA1 Analog Input Module – Product Description

Overview

The Emerson 12P2532X092 (KJ3222X1-BA1) Analog Input Module is engineered for precise data acquisition within DeltaV control systems used in modern industrial environments. Each channel processes 4–20 mA field signals with high accuracy, allowing operators to maintain reliable situational awareness across critical processes. Moreover, the module’s isolated architecture strengthens signal integrity and reduces noise, especially in electrically harsh conditions.

Its support for HART pass-through enables advanced diagnostics from smart transmitters, giving engineers deeper visibility into field conditions. In addition, the compact form factor eases cabinet layout and supports fast module replacement during plant operations. Many facilities choose this module because it remains stable under heavy vibration, thermal cycling, and continuous production loads.
