RELIANCE WR-D4004 MD-D4014B output module

The RELIANCE WR-D4004 is a digital output module used for industrial automation applications. It provides four isolated outputs that can be used to control external devices such as motors, valves, and alarms.

The module is designed to be used with a programmable logic controller (PLC) or other industrial automation device that supports the MODBUS RTU communication protocol. It communicates with the controller over a serial communication link using the MODBUS RTU protocol.

Each output on the module is rated for 24V DC and can sink up to 0.5A of current. The outputs are isolated from the module and from each other, providing protection against electrical noise and ground loops.

To use the module, you will need to configure it with the appropriate parameters using a software tool provided by the manufacturer. This will include setting the communication parameters, the addressing scheme, and the output configuration.

Overall, the RELIANCE WR-D4004 is a versatile and reliable digital output module that can be used in a wide range of industrial automation applications.
