The Emerson KJ3002X1-BG2 (VE4003S5B1) is an 8-channel thermocouple input module for the DeltaV M-series DCS. It features high-accuracy temperature sensing, cold junction compensation, and supports redundant configurations for mission-critical industrial applications.
The Emerson KJ3002X1-BG2 acts as a specialized temperature sensing interface within the DeltaV™ M-series I/O Subsystem. This 8-channel thermocouple module provides high-accuracy data acquisition for critical thermal processes. It enables precise monitoring by converting low-voltage sensor signals into actionable digital values for the DCS.
This module specifically manages millivolt inputs from various thermocouple types. The internal circuitry filters electrical noise to maintain signal purity. Furthermore, it performs cold junction compensation automatically to ensure temperature reading accuracy. This capability allows the DeltaV system to maintain tight control over thermal variables.
