Allen-Bradley 1746-ITB16 Terminal Block Module

Allen-Bradley 1746-ITB16 is a SLC 500 16-point fast‑response digital input module designed for 10–30 VDC sinking signals. It provides sixteen discrete input channels that wire through a removable terminal block (RTB) mounted on the module, enabling compact, serviceable field wiring for sensors, pushbuttons, limit switches, and other 24 VDC automation devices. As part of the 1746 I/O family, the 1746-ITB16 plugs into a compatible 1746 backplane, communicating with the SLC 500 controller to deliver rapid, deterministic input status for real-time control. Key specifications include: 16 DC sinking inputs, voltage range 10–30 VDC, fast‑response performance, and compatibility with 1746-series backplanes and RTB connections. This module is commonly used in legacy industrial automation setups where a compact, easy‑wiring digital input solution is needed to monitor multiple sensors across a single rack.
