The AB 2085-OF4 module can be used to convert digital values from the PLC into corresponding analog signals that can control various field devices such as valves, variable frequency drives, actuators, and other analog-enabled equipment. It provides a means to interface the digital control signals of the PLC with the analog world.

The module supports a variety of analog output signal types, including voltage and current. It offers high resolution and accuracy, allowing precise control of analog output signals within the specified range.

To utilize the AB 2085-OF4 module, you would typically configure it within the programming environment of the ControlLogix PLC. This involves assigning the channels to specific output signals and configuring the desired output scaling and range. The module can then be programmed using ladder logic or other programming languages supported by the ControlLogix platform.
