The Allen-Bradley 1794-OA8K Flex I/O digital output module is an 8-point digital AC output module from the Allen-Bradley Flex I/O system that is designed to provide high-performance digital output solutions to a wide range of distributive applications. The 1794-OA8K digital output module features conformally-coated circuitry that protects the module from harsh industrial environments, making it ideal for use in extreme industrial applications. The 1794-OA8K digital output module requires an external AC power supply with up to 50 Amps of surge current rating for 1/2 cycle to power-up. It has 8 non-isolated output channels with an 85 to 120 Volts AC voltage rating on each channel. It has a maximum on-state current rating of 5 to 75 milliAmps per channel at (35 degrees Celsius), and 4 Amps of maximum current per module. It also has a minimum on-state voltage rating of 85 Volts AC and a maximum voltage rating of 132 Volts AC.
The 1794-OA8K digital output module has a maximum leakage current rating of 2.25 milliAmps in the off-state and a maximum voltage drop of 1 Volt AC at 0.5 Amps of current. This module has a maximum output current surge of 7 Amps for 45 milliseconds, repeatable every 8 seconds. The 1794-OA8K digital output module has a 1/2 cycle maximum signal delay time. The 1794-OA8K digital output module has a maximum power dissipation rating of 4.1 Watts at 0.5 Amps, and of 6.3 Watts at 0.75 Amps and 1 Amp. It can be installed on compatible Allen-Bradley 1794 terminal base units and it can be removed or installed without rewiring the entire base. The 1794-OA8K digital output module comes with 8 yellow status indicators that show the module’s operational status. It has the T4/T4A IEC/North American designated temperature codes, and it comes with an open type of enclosure.
