Allen-Bradley 1756-IB16D 16-Channel DC Input Module

The Allen-Bradley 1756-IB16D is a 16-channel DC input module. It carries the part number 1756-IB16D and is manufactured by Allen-Bradley. This module provides sixteen discrete input points to accept DC signals from field devices such as sensors and switches and to present their binary state to the control system. Designed for integration into industrial automation workflows, the 16-channel format enables scalable monitoring of multiple devices without adding separate small-input modules. The 16 inputs can be mapped into the controller’s input image, allowing software logic to respond to changes in sensor or switch states. Built by a trusted industrial automation brand, the 1756-IB16D supports straightforward wiring and reliable digital input acquisition in applications requiring expanded channel capacity.
