The Emerson DeltaV KJ3222X1-BA1 is an Analog Input (AI) card from the DeltaV series of control systems. Specifically, the KJ3222X1-BA1 card is an 8-channel analog input module that supports 4-20mA signals and HART communication.

This card is designed to interface with field devices that provide analog signals, such as sensors or transmitters. It allows the DeltaV control system to receive and process these analog signals for control and monitoring purposes. The 4-20mA signal range is a common industry standard for transmitting process variables, and the HART communication feature allows for additional data retrieval and configuration capabilities from HART-enabled devices.

The KJ3222X1-BA1 module provides high accuracy and reliability of analog input measurements. Each of the 8 channels on the card can independently process 4-20mA signals and communicate with HART-enabled devices. The data acquired from the field devices can be used for various control and monitoring functions within the DeltaV system.

Overall, the KJ3222X1-BA1 AI card is an integral component of the DeltaV control system, enabling the integration of analog input signals from 4-20mA devices and providing advanced HART communication capabilities for enhanced monitoring and control applications.
