Allen-Bradley 1794-OM8 Flex I/O Digital Output Module 8 Outputs

Product Overview

The 1794-OM8 is a Flex I/O Digital Output Module from Allen-Bradley. It features 8 nonisolated outputs. The module operates at 240V AC nominal voltage. Its output current rating is 4.0A per module. Each output handles up to 500mA. The on-state voltage drop is 1.5V AC at 0.5A. Off-state leakage is 2.5mA maximum. This module uses a terminal base for connections. It supports hot-swappable installation. You can insert or remove it under power. This saves time and avoids system restarts. The module works with various communication networks. Options include ControlNet, DeviceNet, EtherNet/IP, and Universal Remote I/O. LED indicators show status for each channel. XT versions offer extreme environment operation. This reduces panel and maintenance costs.

Application Scenarios

Use the 1794-OM8 in manufacturing plants and industrial facilities. It controls AC loads like motors, valves, and solenoids. The module fits in Flex I/O systems. It connects to PLCs and DCS platforms. Typical applications include conveyor systems, packaging machines, and assembly lines. The module also works in harsh environments with XT options. Its hot-swap capability keeps production running during maintenance.
