More Information

Overview Manuals Power Environment Handling Application
  • Eight channels accept documented thermocouple types and low-level millivolt sources
  • Local or externally configured cold-junction compensation supports temperature measurement
  • Two four-channel groups provide the documented isolation arrangement

KJ3002X1-BG2 is an Emerson thermocouple/mV input card designed for the DeltaV M-series Traditional I/O platform.

The card acquires low-level temperature and voltage signals with 16-bit conversion, open-sensor detection, and the documented cold-junction compensation options.

Before installation or replacement, verify the complete catalog number, actual label, thermocouple type, terminal block, cold-junction method, polarity, channel grouping, and saved DeltaV configuration.

Availability, condition, price, and shipping time for KJ3002X1-BG2 are confirmed during quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which sensors can Emerson KJ3002X1-BG2 accept?
It supports thermocouple types B, E, J, K, N, R, S, and T, an uncharacterized thermocouple mode, and low-level millivolt sources.
Does Emerson KJ3002X1-BG2 provide cold-junction compensation?
Yes. Local compensation is available with compatible terminal hardware, and external compensation can be implemented by configuring one channel.
How does Emerson KJ3002X1-BG2 detect an open sensor?
The documented detection current is less than 70 nA and the published open-sensor detection time is 10 seconds.
Are all channels of Emerson KJ3002X1-BG2 isolated from one another?
No. The card isolates channel groups 1–4 and 5–8 from each other; channels within each four-channel group are not individually isolated.
What should be checked when moving a thermocouple to Emerson KJ3002X1-BG2?
Confirm thermocouple type, polarity, extension-wire material, terminal block, cold-junction method, channel grouping, and the DeltaV channel definition.
Does Emerson KJ3002X1-BG2 require calibration?
The DeltaV M-series product data states that calibration is not required for this thermocouple/mV input type.
Can 12P1731X062 be treated as an official alias for Emerson KJ3002X1-BG2?
Only when both identifiers are visible on the actual product label or covered together by a manufacturer document. The available official functional data confirms KJ3002X1-BG2 but does not establish that one 12P suffix applies to every card.
