Features:
- Flex I/O Digital Output Module
- 8 Nonisolated Outputs, a 240V AC Output Voltage nom., and a 4.0A Output Current Rating
- It also operates with a 1.5V AC @ 0.5A On-state Voltage Drop max. and a 2.5mA Off-state Leakage max
The Allen-Bradley 1794-OM8 is a 1794 FLEX digital AC output module. It is installed inside the terminal bus for connecting field devices and the I/O bus. Because this I/O module requires no direct wiring, it can be plugged and unplugged while the system is powered on. This saves time and avoids efficiency losses due to system restarts.
The 1794-OM8 module has 8 output ports. This module features a snap-on mounting system for DIN rail installation. It offers various communication options, including ControlNet, DeviceNet, EtherNet/IP, and universal remote I/O.
The 1794-OM8 Allen Bradley Flex I/O Digital Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Each channel of the 1794-OM8 module is equipped with 16 yellow LED status indicators to display the corresponding input device and output signal.
A standard XT module version is also available for extreme environments, reducing panel and maintenance costs. Its operating temperature range is 0 – 55 °C (32 – 131 °F), and relative humidity range is 5 – 95% (non-condensing).
- AC Load Control: Used for direct switching of industrial actuators operating on 220–240V AC power, typically eliminating the need for intermediate relays.
- Distributed I/O Systems: Serves as a remote control node within the FLEX I/O component, allowing output control to be placed closer to the machine, reducing cabling complexity.
- High-Voltage Discrete Signals: Ideal for managing field devices such as alarms, indicator lights, and heavy-duty contactors in protected cabinet environments.
- Maintenance Optimization: Supports Live Removal and Plug-in (RIUP), allowing modules to be hot-swapped without interrupting field cabling or shutting down the rest of the system.
