Product Overview

The Emerson KJ3002X1-BA1 (Part Number 12P0680X122) is a high-performance 8-channel Analog Input Module engineered for the DeltaV™ M-series I/O subsystem. This module is a core component of the Distributed Control System (DCS), specifically designed to interface with field transmitters to monitor essential process variables such as pressure, temperature, level, and flow.

This module supports standard 4-20 mA DC signals and is fully integrated with HART (Highway Addressable Remote Transducer) protocol capabilities. The HART functionality allows for the transmission of digital diagnostic data over the existing analog wiring, enabling maintenance teams to perform remote configuration, calibration, and health monitoring of smart field devices without interrupting the primary process signal.
