Brief Product Description

The Emerson KJ3002X1-BA1 (12P0680X122) is a high-performance M-series analog input module featuring 8 channels and full HART communication support. It provides precise data acquisition for critical process variables such as pressure, flow, and temperature within the DeltaV™ Distributed Control System.

​Product Description

Integrated HART Data Acquisition

The Emerson KJ3002X1-BA1, identified by part number 12P0680X122, functions as a cornerstone for signal processing within the DeltaV™ M-series I/O subsystem. This module supports 8 channels of 4-20 mA analog signals, allowing for high-density monitoring of field instrumentation. Because it includes native HART protocol support, the card enables engineers to access advanced device diagnostics and perform remote calibrations without additional handheld communicators. This deep integration simplifies maintenance workflows and significantly enhances the predictive diagnostic capabilities of the DCS environment.

Optimized Signal Integrity and Precision

Process accuracy relies on the 12P0680X122 module’s ability to filter noise and manage signal conversion. The module utilizes built-in electrical isolation to protect the system backplane from field-side surges and electromagnetic interference. Consequently, operators receive stable and highly accurate readings for critical variables like flow rates and vessel pressures. Furthermore, the card’s high-resolution analog-to-digital conversion ensures that even minute fluctuations in process conditions are captured, allowing the control logic to respond effectively to dynamic industrial changes.

Industrial Durability and Environmental Resilience

Emerson engineered the KJ3002X1-BA1 to maintain reliable operation in challenging industrial climates. The module effectively operates across an impressive temperature range of -40°C to +70°C and withstands non-condensing humidity levels up to 95%. This ruggedized construction ensures that the I/O subsystem remains functional in remote mounting locations or harsh process areas. While the product reached a discontinued status in late 2018, it remains a vital component for maintaining and expanding legacy DeltaV systems, offering a reliable path for sustaining operational control without a full system overhaul.
