Description

Product Overview

The Allen-Bradley 1794-IM8 is an 8-channel 220V AC Digital Input Module for the Flex I/O system. It accepts 240V AC nominal inputs with 13.21mA on-state current and 22.3kΩ input impedance. This compact module mounts on DIN rail or screw panel for flexible installation in industrial control systems.

Core Functionality

The 1794-IM8 provides 8 nonisolated AC input channels for sensing field devices such as switches, pushbuttons, and limit switches. It operates with a nominal on-state voltage of 240V AC and maximum off-state voltage of 40V AC. The module requires a 1794-TBN terminal base for wiring connections and communicates via the Flexbus at 30mA @ 5V DC. It supports both screw mount and DIN rail mount configurations.
