Process Temperature Measurement Solution — EMERSON KJ3002X1-BG2 | DeltaV Series
Where This Product Is Used
The EMERSON KJ3002X1-BG2 (P/N: 12P1731X032) Thermocouple Input Module is deployed in mission-critical temperature measurement loops across a wide range of industrial processes. Typical application environments include:
- Oil & Gas Upstream/Downstream: Wellhead temperature monitoring, crude distillation column profiling, and fired heater tube-skin measurement.
- Chemical & Petrochemical Plants: Reactor temperature control, heat exchanger performance monitoring, and exothermic process safety interlocks.
- Power Generation: Boiler flue gas temperature, steam turbine bearing monitoring, and combustion optimization loops.
- Pulp & Paper / Food & Beverage: Dryer section temperature profiling and pasteurization process control.
- Pharmaceutical Manufacturing: Sterilization cycle validation and clean-in-place (CIP) temperature verification.
Wherever a DeltaV DCS system governs temperature-critical processes, the KJ3002X1-BG2 is the OEM-specified I/O card of choice.

Why Engineers Specify This Model
- Native DeltaV Integration: Plug-and-play recognition within DeltaV Explorer — no manual address configuration or external signal conditioners required.
- Per-Channel TC Type Selection: A single module can simultaneously handle mixed thermocouple types (e.g., K-type on channels 1–4, J-type on channels 5–8), reducing BOM complexity.
- Automatic Cold Junction Compensation (CJC): Eliminates the need for external CJC hardware, improving accuracy and reducing panel wiring.
- Open-Wire Fault Detection: Each channel independently detects open-circuit faults and drives the process value to a configurable safe state — critical for SIL-rated safety loops.
- Hot-Swap Capable: Modules can be replaced under power without shutting down the controller, minimizing process downtime during maintenance windows.
- Proven Field Reliability: Widely deployed in Emerson DeltaV installations globally since the S-Series platform launch; extensive installed base ensures long-term spare parts availability.

Application-Specific FAQ
Q: Is the KJ3002X1-BG2 compatible with DeltaV Version 14.x and later?
A: The KJ3002X1-BG2 is a legacy S-Series I/O module. Compatibility with DeltaV v14+ should be confirmed against Emerson’s release notes. For newer installations, Emerson’s Electronic Marshalling (CHARM) platform may be specified instead. Contact us for guidance.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The KJ3002X1-BG2 is a standard I/O module, not a certified SIS module. For SIL-rated safety loops, Emerson’s DeltaV SIS platform with dedicated safety I/O (e.g., KJ3002X1-BH2 or equivalent SIS-certified variant) must be used.
Q: What is the difference between KJ3002X1-BG2 and KJ3002X1-BG1?
A: The BG2 revision incorporates minor firmware and hardware updates over BG1. In most DeltaV installations, the revisions are interchangeable, but always verify with your site’s DeltaV version compatibility matrix before substitution.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a 90-day functional warranty on all modules. Units that fail under normal operating conditions within the warranty period will be replaced or refunded. See our full warranty policy at Konmask.com.
Q: Can I return the module if it doesn’t fit my system?
A: We accept returns within 30 days of delivery for unused, uninstalled modules in original condition. Please contact support@konmask.com to initiate a return authorization.
