Emerson DeltaV is a distributed control system (DCS) commonly used in industrial automation and process control applications. The KJ2201X1-PW1 is a specific module used in the DeltaV system.

The KJ2201X1-PW1 module is a Channel Isolated 8-Point Analog Output Card. It provides eight isolated analog output channels, which can be used to control various process variables in a plant. Each channel on the module is capable of providing a current or voltage output signal to interface with field devices.

The module is designed to fit into a DeltaV system's I/O chassis, where it communicates with the system's controller and other modules. It uses communication protocols such as MODBUS or OPC to exchange data with the control system.
