The Allen-Bradley 1734-OA2 point I/O 120 to 240 Volts AC output module is a digital output module with 8 key-switch positions and two non-isolated current sourcing outputs. It has an external DC voltage supply of 120 to 220 Volts DC at 60 Hertz and an isolation voltage of 240 Volts AC with a reinforced insulation type tested at 3250 Volts DC for 60 seconds from field to system. It has an open-style enclosure which is suitable for its power dissipation rate of 2W at 264 Volts AC and a thermal dissipation of 6.8 BTU/hour at 264 Volts AC. The 1734-OA2 is mounted with a 7 pounds on an inch terminal base screws using a DIN rail on either the 1734-TB, 1734-TBS, 1734-TOP, or the 1734-TOPS wiring base assembly.

The 1734-OA2 features electrical rating with an on-state voltage range between 120 to 220 Volts AC, which peaks at 264 Volts AC and an on-state current of 10mA per channel that maxes out at 750mA per channel. It has a drop voltage of 1.0 Volts at 0.75mA and a maximum leakage current of 2.7mA at 264 Volts AC. It has an inrush current of 16 Amps for 100 milliseconds, recurring every 3 seconds, and a half cycle signal delay time. The 1734-OA2 operates best at a temperature range between -4 and 131 degrees Fahrenheit, but it will steadily de-rate 13% at a time for any temperature value exceeding 55 degrees Celsius. It has a storage temperature range between -40 and 185 degrees Fahrenheit, at 5 to 95% non-condensing relative humidity. It has an operational shock rate of 30G and a maximum vibration of 5G at 10 to 500 Hertz. The 1734-OA2 weighs 1.09 ounces, and it has dimensions of 2.21 x 0.47 x 2.97 inches.
