Product Overview

The Emerson KJ3002X1-BB1 analog output module, identified by order number 12P0683X082, is an 8-channel 4–20 mA output card engineered for the DeltaV™ M-series I/O subsystem. This module is designed to generate precise analog control signals for field devices such as control valves, positioners, actuators, and variable speed drives within distributed control systems.

Built for integration into DeltaV DCS architectures, the module converts digital control commands into stable current outputs, supporting accurate and repeatable process control. Although this hardware was discontinued in 2018, it remains widely deployed and is commonly sourced as a spare or replacement component for existing DeltaV M-series installations.
