About 1794-OA8
The 1794-OA8 output module is a digital output module that operates on AC power. This module has been designed and manufactured by Allen-Bradley/Rockwell Automation in the Flex I/O series. The 1794-OA8 output module is rated to operate safely in Class 1, Division 2, Groups A, B, C, and D rated operating environments. The 8 outputs on the 1794-OA8 AC output module are not isolated. The minimum AC output voltage rating of the 1794-OA8 output module is 85 Volts AC, the maximum AC output voltage rating is 132 Volts AC, and the nominal input voltage is 120 Volts AC. Its on-state current ratings are 5 milliamps minimum per output and 500 milliamps maximum per output at 55 degrees Celsius or 750 milliamps maximum per output at 35 degrees Celsius.
The Allen-Bradley/Rockwell Automation 1794-OA8 AC digital output module can handle a surge current of up to 7 Amps for 40 milliseconds which is repeatable every 8 seconds and a FlexBus current of 80 milliamps at 5 Volts DC. The outputs on the 1794-OA8 digital output module are not isolated but the whole module supports 120 Volts AC of continuous isolation voltage from the field to the backplane and 1250 Volts AC of isolation voltage for 60 seconds. The 1794-OA8 module weighs about 3.84 ounces and its dimensions are 3.7 x 3.7 x 2.7 inches. It has 8 yellow LED status indicators on the field side. There is 1 LED indicator for each output. The 1794-OA8 output module does not come with an enclosure, so it should be installed in one for safe operation in industrial settings.
The Allen-Bradley 1794-OA8 AC output module is a member of the Flex I/O series of industrial input and output modules. Its nominal voltage rating is 120 Volts AC and its operating voltage range is from 85 to 132 Volts AC.
