Installation Guidelines

Mounting: Secure the compatible FLEX I/O terminal base onto a 35 x 7.5mm DIN rail.
Keyswitch: Set the keyswitch on the terminal base to position 8 to ensure mechanical compatibility with the 1794-OM8 module.
Module Insertion: Align the module with the terminal base slots, ensuring pins are straight, and press firmly until the latching mechanism clicks into place.
Wiring: Ensure all field power is disconnected before installing or removing the module. Use appropriate wire gauges for the terminal base connections.
Environment: Ensure adequate ventilation for heat dissipation; avoid mounting near high-EMI sources or extreme heat zones.

FAQ

What is the primary function of the 1794-OM8?

The 1794-OM8 is a digital output module used to interface a FLEX I/O system with 240V AC field devices, allowing the controller to switch high-voltage loads.

Is this module hot-swappable?

Yes, the FLEX I/O architecture allows for the electronic module to be removed and replaced while the system is powered, provided it is mounted on a compatible, pre-wired terminal base.

What is the maximum current capacity?

The module supports a maximum of 500 mA per output, with a total module current limit of 4.0 A.
