The 1756-IB16 module provides 16 digital input channels. It can be used to monitor the status of various devices, such as limit switches, push buttons, proximity sensors, and other types of sensors and switches in a control system. Each input channel can be individually configured for different signal types, such as sinking or sourcing inputs.

The module uses a backplane connection to communicate with the ControlLogix controller, sharing power and data over the ControlLogix chassis. It supports a wide range of voltage levels for the inputs, typically 24V DC, ensuring compatibility with various industrial control systems.
