Core Redundant Output for Critical Control

The Emerson KJ3221X1-BA1 12P2531X132 VE4035S2B1 is a 4-20mA HART Redundant Analog Output Module for DeltaV systems. This module provides two fully independent output channels for mission-critical control loops. If one channel fails, the other automatically maintains the analog signal without interruption. Consequently, it ensures exceptional availability for controlling valves, drives, and recorders in process automation.

High Accuracy and HART Communication

This module delivers high output accuracy of ±0.1% of reading for precise process control. It features a 12-bit digital-to-analog converter (DAC) for smooth and stable signal generation. The KJ3221X1-BA1 supports the HART protocol for remote configuration, calibration, and diagnostics. Furthermore, its channels are electrically isolated from each other to maximize reliability and prevent fault propagation.

Detailed Technical Specifications

Designed for harsh industrial environments, the module operates reliably across a wide temperature range. Each channel includes LED indicators for immediate visual status and fault identification. The following table details its complete electrical, performance, and environmental parameters.

Application and Integration Benefits

Install this module in DeltaV racks to control critical final control elements like control valves. Its HART capability allows asset management systems to access device intelligence and health data. The Emerson KJ3221X1-BA1 module is engineered for maximum uptime in oil & gas, chemical, and power generation applications. Therefore, it is an essential component for building fault-tolerant control strategies in any high-availability process plant.
