The 1794-OE12 is a digital output module manufactured by Allen-Bradley as part of their Flex I/O series of modular input/output systems. The module is designed to interface with a variety of field devices and provide control signals based on the input data received from the controller.

Number of Channels: The module has 12 digital output channels, allowing it to control up to 12 different devices or components.

Current Rating: Each channel of the module has a current rating of 0.5 Amps at 24 volts DC or 0.2 Amps at 120 volts AC.

Current Rating: Each channel of the module has a current rating of 0.5 Amps at 24 volts DC or 0.2 Amps at 120 volts AC.

Output Type: The outputs are typically relay-based, providing electrical isolation and allowing the module to switch high-current loads.

Diagnostic LEDs: The module features status LEDs for each channel to indicate the ON/OFF status and provide diagnostic information.

Wiring Options: The module supports multiple wiring options, including direct output wiring or connection to a terminal base with prewired cables.

Communication Protocol: The module communicates with the controller using the Allen-Bradley Remote I/O (RIO) or DeviceNet protocol.

Configuration: The module can be configured and programmed using Allen-Bradley software tools, such as RSLogix or Studio 5000, to define the behavior and logic for each output channel.
