Emerson KJ3002X1-BG2 Thermocouple Module

Configured for direct analog signal acquisition in Emerson DeltaV DCS environments, the Emerson KJ3002X1-BG2, also cataloged as the KJ3002X1-BG2 Thermocouple Module, provides direct physical/electrical execution.

Hardware Specifications

Process Control and DCS Characteristics

• Converts millivolt inputs from field thermocouples into digitized temperature values for system controller processing.
• Features integrated cold junction compensation (CJC) algorithms to maintain signal accuracy across varying cabinet temperatures.
• Utilizes channel-to-channel isolation architecture to eliminate ground loops and reject common-mode voltage spikes across industrial field cabling.
• Incorporates 4-20 mA HART loop protocol carrier compatibility across system backplane interfaces for extended instrument diagnostic passthrough.

Frequently Asked Questions

Q: How does the KJ3002X1-BG2 module perform cold junction compensation?

A: Cold junction compensation is maintained via internal thermal sensors embedded on the terminal block assembly, correcting for ambient variations at the wiring termination point.

Q: Can the module be inserted or removed while the terminal base is powered?

A: Yes, DeltaV M-series I/O modules support power-on insertion and removal (removal under power) when installed on compatible I/O carrier bases.

Field Installation Guidelines

• Secure the module onto the DeltaV M-series I/O carrier until the locking mechanisms fully engage with the backplane base.
• Ensure shielded thermocouple wiring is grounded at a single point to prevent high-frequency noise interference on low-millivolt input channels.
• Maintain a minimum bending clearance for field wiring to prevent mechanical stress on terminal connectors.
