Emerson KJ3201X1-BA1 is a DI (Digital Input) card used in industrial automation and control systems. It is designed to interface with 24V dry contact signals or discrete inputs from field devices.

The KJ3201X1-BA1 DI card provides multiple channels, typically 16 channels, for receiving digital input signals from sensors, switches, or other devices that provide a dry contact closure. These inputs are commonly used to monitor the status or state of various equipment or processes in the system.

The DI card can be integrated into an Emerson DeltaV system, allowing the user to monitor and control the digital input signals. It provides a reliable and accurate means of collecting input information, which can then be used for further processing, control, or alarming purposes.
