This module features the following technical specifications:

The 1734-OA4 120 to 240 Volts AC output module by Allen-Bradley is a digital POINT I/O module with 4 sourcing, non-isolated outputs with 0.75 Amps per channel sourcing voltage. The 1734-OA4 can be used with DeviceNet and a PROFIBUS adapter for enhanced network capability and data sharing. Additionally, ControlNet and EtherNet/IP adapters can also be used with the 1734-OA4. It has a distinct on-state voltage of 74 Volts AC which can go through a range of 120 to 240 Volts AC and it maxes out at 264 Volts AC. Consequently, it has a maximum drop voltage of 1.0 Volts AC at 0.75 Amps with an on-state current of 10mA per channel which maxes out at 750mA per channel and 2 Amps per module.

The 1734-OA4 has an output current rating of 750 mA per channel and 2 Amps per module, with a leakage current of 2.7 mA at 264 Volts AC. The 1734-OA4’s maximum output of 2 Amps per module at a temperature limit of 113 degrees Fahrenheit, but it will derate uniformly at 30% to 1.4 Amps per module at any temperature above 131 degrees Fahrenheit. It has a surge current of 16 Amps for 100 milliseconds that is repeatable every 10 seconds. The 1734-OA4 module is installed on the base wiring assembly and it has a POINT BUS current of 75 mA at 5 Volts DC. It has a maximum power dissipation of 3.2 Watts at 264 Volts AC and a thermal dissipation of 11.9 BTU/hour at 264 Volts AC. The 1734–OA4’s approximate dimensions are 2.21 x 0.47 x 2.97 inches and its approximate weight is 1.09 ounces.
