Product Description

The Emerson KJ3101X1-BB1 (12P1866X042) is a high-performance DeltaV™ Analog Input (AI) Module designed to provide precise signal acquisition for Emerson’s DeltaV distributed control system (DCS). It offers 8 isolated analog input channels for reliable connection to field instruments, including transmitters and sensors.

Moreover, the module converts analog signals, typically 4–20 mA, into digital values that the DeltaV controller can process with high accuracy. Each channel is galvanically isolated, minimizing interference and ensuring signal integrity across complex industrial environments.

In addition, the KJ3101X1-BB1 supports HART pass-through communication, enabling access to diagnostic and configuration data from smart field devices without disrupting normal operations. Its robust design allows operation in hazardous areas (Zone 2 / Class I Div. 2) and harsh industrial conditions, including oil & gas, chemical, power generation, and steel manufacturing industries.
