Allen-Bradley 1746-IB16 16-Point Digital Input Module

The Allen-Bradley 1746-IB16 is a 16-channel digital input module for SLC 500 PLCs that monitors 24V DC discrete signals in a chassis-mounted format. It provides 16 input points, accepts 24V DC inputs, and supports sourcing and sinking DC inputs, making it suitable for sensing sensors, switches, and field devices in industrial automation panels and production lines. Typical applications include conveyors, packaging machines, assembly lines, and process equipment where accurate input signal processing is required, and it integrates with Allen-Bradley SLC 500 systems for reliable input monitoring. Common replacements in this family include the 1746-IB8, 1746-IB32, and 1746-ITB16.
