Description
Product Description
The Allen-Bradley 1794-IM8 is an AC digital input module from the FLEX I/O distributed I/O platform, engineered for high-voltage signal monitoring in industrial automation systems. This module accepts eight non-isolated AC input channels and is optimized for 240V AC signal detection in machine control and process applications.
Designed for compact FLEX I/O architectures, the 1794-IM8 offers reliable input processing with low backplane current consumption and integrated channel status indication. The module interfaces directly with field AC devices such as switches, pushbuttons, sensors, auxiliary contacts, and pilot devices operating within standard industrial voltage ranges.
Its modular construction allows flexible installation with compatible terminal base units including 1794-TBN and 1794-TBNK.
