Here's a breakdown of its features:

Input Channels: The "IB16" in the module's name stands for "Input, 16 points." This means it has 16 digital input channels that can be used for sensing the state of devices or processes.

Output Channels: The "OB16P" in the module's name stands for "Output, 16 points, sourcing." This indicates that it has 16 digital output channels that provide sourcing output signals to control actuators or devices.

Input Type: The 1794-IB16xOB16P module supports digital inputs, which means it can read binary states (on/off or high/low) from connected devices or sensors.

Output Type: The module supports digital outputs, which means it can provide binary output signals (on/off or high/low) to control external devices or actuators.

Compatibility: The 1794-IB16xOB16P module is designed to work specifically with the ControlLogix platform, which is an advanced programmable automation controller (PAC) series from Allen-Bradley.

Communication: The module communicates with the ControlLogix controller over an I/O chassis-mounted backplane. It uses the series B communication interface.
