Here are some key features of the 1756-IR12 module:

Isolation: The module offers channel-to-channel isolation, which helps prevent noise interference and signal distortion between channels.

Measurement Range: The module supports a variety of measurement ranges, including voltage and current ranges. The specific ranges supported can be configured in the module's configuration software.

Resolution: It provides high-resolution measurements with 16-bit analog-to-digital converters (ADCs). This allows for accurate and precise measurements of analog signals.

Diagnostic Capabilities: The module includes diagnostic features that can help with troubleshooting and maintenance. It provides status indicators for each input channel, allowing users to quickly identify any issues.

Configuration: The module can be easily configured using Rockwell Automation's programming software, such as RSLogix 5000. Through the software, users can set the range, scaling, and other parameters for each input channel.
