Allen-Bradley 1746-IB16 C01 Programmable Logic Controller Module

Allen-Bradley 1746-IB16 C01 is a SLC 500 digital input module that provides 16 discrete input points for reading 24 VDC field signals into an SLC 500 controller. This sinking input module accepts 10–30 VDC signals and presents each input as a separate digital point, suitable for sensors, switches, and other digital devices. It uses the standard 1746 backplane, drawing a backplane current of about 85 mA at 5 V, with an off-state current around 1 mA per channel. The module features typical input response timing of roughly 8 ms, enabling timely detection of state changes in automation tasks. The 1746-IB16 is used in industrial automation to convert sensor contacts and switches into binary CPU inputs for ladder logic, sequencing, and interlocks, and is compatible with Rockwell Automation SLC 500 processors alongside other 1746 I/O modules. The C01 revision identifies a specific manufacturing revision of this part. This module is designed for DC-sensing applications and is commonly deployed in machinery, conveyors, and packaging lines where 24 VDC digital signals must be reliably captured by the PLC.
