The Emerson DeltaV KJ3001X1-BJ1 is a discrete output module for the DeltaV distributed control system (DCS) manufactured by Emerson Process Management. It is a high-side module specifically designed for controlling discrete devices that require 24 VDC power supply.

Here are some key features of the KJ3001X1-BJ1 module:

1. Type: Discrete Output (DO) Module

2. Power Supply: 24 VDC

3. Output Type: High Side

4. Number of Outputs: 8

5. Connector Type: Removable terminal blocks

6. Backplane Connection: DeltaV Virtual I/O Module (VIM) card slot

7. Compatibility: Designed to work with the Emerson DeltaV system

The KJ3001X1-BJ1 module is commonly used in industrial control applications where discrete devices such as solenoid valves, contactors, motors, and indicator lights need to be controlled. The high-side configuration ensures that the module can handle higher voltages and can switch power to the devices being controlled.
