Product Description
The Allen-Bradley 1746-IB8 is a DC digital input module from the SLC 500 family (Bulletin 1746), providing eight 24 V DC sinking input channels. It is designed to monitor the ON/OFF status of field devices such as push buttons, limit switches, proximity sensors, and other discrete DC signals.
Installed in a standard SLC 500 chassis, the 1746-IB8 communicates with the processor via the backplane. Compact yet robust, this module ensures fast and reliable detection of DC signals in manufacturing, packaging, and process automation applications. While discontinued by the manufacturer.
