Product Overview

The Emerson VE4003S6B1, categorized under model KJ3002X1-BF1 and part number 12P1732X042, is a precision RTD (Resistance Temperature Detector) Input Card engineered for the DeltaV™ M-series I/O subsystem. This module serves as a high-accuracy interface for temperature sensing, converting resistance signals from field-mounted RTDs into digital data for the Distributed Control System (DCS). It is specifically designed to support 8 channels of 2-wire, 3-wire, or 4-wire RTD sensors, ensuring flexible integration with various instrumentation standards.

Built to maintain thermal stability in demanding process environments, the KJ3002X1-BF1 provides essential signal conditioning and linearization. While the M-series hardware platform was officially retired from active production in December 2018, this RTD card remains a cornerstone component for the maintenance and continued operation of legacy DeltaV installations across the global energy and manufacturing sectors.
