About 1746-OA16/D

The 1746-OA16 Series D module is a digital AC output module manufactured by Allen-Bradley/Rockwell Automation as part of the SLC 500 series. It runs on an operating voltage of 85 to 265 Volts AC at a frequency of 47 to 63 Hertz. It has 16 outputs, with each group having 8 points. This module requires a backplane current load of 0.37 Amps at 5 Volts DC. The Allen-Bradley 1746-OA16 Series D digital AC output module comes with a maximum continuous current of 0.5 Amps per point and of 8 Amps per module at 86 degrees Fahrenheit and 0.25 Amps per point and 4 Amps per module at 140 degrees Fahrenheit. The module is generally utilized with 120 to 240 Volts AC output voltage in the SLC 500 series systems. This module can digitally receive and store converted analog data through its data image table, which also allows for data retrieval by both modular as well as fixed SLC 500 processors. The 1746-OA16 Series D module can support connections with up to a maximum of 8 sensors.

The 1746-OA16 Series D module features removable terminal blocks which help to eliminate the need to disconnect the wires anytime the module has to be replaced. This module also comes with filter circuitry as well as the optical coupling that helps to reduce noise. Its output values are accessible through the SLC 500 processors that use the Ladder Logic. Additionally, troubleshooting is made even easier through the LED indicators which show the module’s output status values. Also, the SLC 500 system is designed specially as sharing-based hardware that comprises a wide range of combinations of both digital and analog I/O, thus helping to save space and costs.
