Emerson VE4012S2B1 KJ3102X1-BA1 Analog Output Module – Product Description

Overview

The Emerson VE4012S2B1 (KJ3102X1‑BA1) is an 8-channel isolated analog output module designed for the DeltaV™ distributed control system (DCS). It converts digital control signals into precise 4–20 mA analog outputs to operate control valves, actuators, and other field devices. Moreover, each channel is galvanically isolated, ensuring signal integrity and reducing interference. In addition, the module supports HART pass-through communication, allowing diagnostics and configuration of smart field devices directly through the DeltaV system.
