The 1746-NIO4V module is an analog voltage or current input/output module with 4 input and 4 output channels. It is designed to interface with analog sensors and actuators in an industrial environment. The module supports both voltage and current input signals, allowing you to connect a wide range of analog devices.

Here are some key features of the 1746-NIO4V module:

Input Channels: It has 4 analog input channels that can accept voltage or current signals. Each channel can be configured individually for either voltage or current modes.

Output Channels: It also has 4 analog output channels that can generate either voltage or current signals. Each output channel can be configured independently.

Communication: The 1746-NIO4V module communicates with the SLC 500 processor through a backplane connection. It can be easily configured and programmed using RSLogix 500 programming software.

Compatibility: The module is designed specifically for the Allen-Bradley SLC 500 PLC platform and can be used with various SLC 500 processors, such as the 1747-L524, 1747-L542, or 1747-L543.
