Description

The Emerson DeltaV KJ3002X1-BG2 (assembly 12P1731X062) is a high-precision 8-channel analog input module designed for thermocouple and millivolt (mV) signal measurement. As a core component of the DeltaV distributed control system, this module provides reliable thermal data acquisition for critical industrial processes, including power generation, oil and gas refining, and chemical manufacturing. It features integrated cold junction compensation and high-resolution signal conversion to ensure accuracy in demanding control loops.

Features

  • 8-channel input capacity for thermocouple and millivolt sensors.
  • Integrated cold junction compensation for improved measurement precision.
  • Factory-calibrated design eliminates the need for manual field calibration.
  • Mechanical rotary keying (Position B2) to prevent incorrect terminal block installation.
  • Supports hot-swapping capability when installed with compatible power supply carriers.
  • Ruggedized construction rated for ISA-S71.04 Class G3 corrosive environments.

Applications

This module is widely utilized in process automation environments requiring high-density temperature monitoring. Typical applications include furnace temperature control, boiler monitoring, heat exchanger performance tracking, and general-purpose millivolt signal acquisition in hazardous area installations.

Installation Guidelines

  • Ensure the system power is off before inserting or removing the module from the carrier, unless performing a hot-swap in accordance with DeltaV system specifications.
  • Verify the mechanical keying position (B2) on the terminal block matches the module to prevent improper electrical connection.
  • Handle the module using standard ESD (Electrostatic Discharge) precautions to protect internal components.
  • Ensure the module is securely seated in the I/O carrier to maintain proper grounding and communication bus contact.
  • Maintain adequate ventilation in the cabinet to ensure the ambient temperature remains within the 0 to 60 deg C operating range.

Compliance and Certifications

The KJ3002X1-BG2 is rated for use in hazardous environments under the following certification: II 3 G EEx nL IIC T4 (Nemko 02ATEX431U).

FAQ

Does this module require manual calibration?
No, the KJ3002X1-BG2 is factory-stabilized and does not require manual calibration during its operational lifespan.

Is this module hot-swappable?
Yes, the module supports hot-swapping when used in conjunction with a compatible DeltaV power supply carrier, provided that specific inductance limits are observed.
