Allen-Bradley 1756-IB16I 16-Point Input Module

The Allen-Bradley 1756-IB16I is a ControlLogix 16-point, isolated DC input module that accepts 10–30 VDC signals with a nominal 24 VDC level. Each of its 16 input channels is independently isolated, helping prevent cross‑talk and grounding issues when wiring multiple sensors on the same rack. The module uses a 36‑pin field interface and is designed to plug into a 1756 ControlLogix backplane, feeding digital input data to the controller. It supports 12/24 V DC sink/source operation per channel, enabling flexible wiring with a variety of 24 V devices and sensors. This compact 16‑point input card is well suited for reading binary signals from proximity sensors, limit switches, pushbuttons, and other standard control devices in mid‑size automation applications such as manufacturing lines, material handling, and packaging systems, all within a Rockwell Automation ControlLogix environment.
