Emerson KJ3223X1-BA1 Series 2 AI 16-Channel 4-20mA Module

Product Introduction

Emerson KJ3223X1-BA1 is a DeltaV Series 2 Analog Input Card designed for reliable 2-wire current signal measurement.

This module provides 16-channel 4-20 mA analog input capability for industrial process control systems.

The card supports continuous field monitoring for pressure, flow, level, and temperature transmitters.

KJ3223X1-BA1 uses a compact I/O architecture for high-density signal acquisition.

It helps engineers reduce cabinet space while maintaining stable measurement performance.

Global PLC Spare HUB's Insight:

In field applications, this card often connects with 2-wire transmitters in chemical plants, power stations, and oil processing units.

For example, when a refinery upgrades old transmitter loops, engineers can replace multiple input modules with a higher-density KJ3223X1-BA1 Series 2 AI module.
