Here are some key features of the 1756-IB16I module:

Inputs: The module has 16 input points, which are compatible with both sinking and sourcing inputs. Each input point can be used to monitor a discrete signal from an external device.

Voltage Range: The module supports a wide range of input voltages. Typically, it can handle input voltages of 10-30V DC.

Indicators: Each input point on the module has a corresponding indicator LED to provide visual feedback on the status of the input signal.

Wiring: The 1756-IB16I module uses removable terminal blocks for connecting field wiring. These terminal blocks make it easier to install and maintain the module.

Compatibility: The 1756-IB16I module is designed to work with Allen-Bradley ControlLogix PLCs and requires a ControlLogix chassis for installation. It communicates with the PLC processor over the backplane, allowing for rapid data exchange.
