1734-OA2 Allen Bradley:
1734-OA2 Rockwell PLC Module Supply
The Allen-Bradley 1734-OA2 point I / O 120 to 240 volt AC output module is a digital output module with eight key switch positions and two non-isolated current outputs. The 1734-OA2 has an external DC power supply of 120 to 220 volts DC at 60 Hz and an isolation voltage of 240 volts AC, and has a reinforced insulation type that has been tested at 3,250 volts DC for 60 seconds from the field to the system. The 1734-OA2 has an open housing suitable for 2W power consumption at 264V AC and 6.8 BTU / hour heat dissipation at 264V AC. Using a 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS wiring base assembly, mount the 1734-OA2 on the 7-inch terminal base screws with a 7-pound weight.
1734-OA2 has rated electrical characteristics. Its on-state voltage ranges from 120 to 220 volts AC, with a peak current of 264 volts AC. The on-state current of each channel is 10 mA, and the maximum of 1734-OA2 per channel is The on-current is 750mA. The voltage drop at 0.75mA is 1.0V, and the maximum leakage current at AC 264V is 2.7mA. The 1734-OA2 has a 16 amp surge current, lasts 100 milliseconds, repeats every 3 seconds, and has a signal delay of half a cycle. 1734-OA2 works well in the temperature range of -4 to 131 degrees Fahrenheit, but for any temperature value exceeding 55 degrees Celsius, it will steadily decrease by 13% at a time. It has a storage temperature range of -40 to 185 degrees Fahrenheit and a non-condensing relative humidity of 5 to 95%. At a frequency of 10 to 500 Hz, the 1734-OA2 has an operating shock rate of 30G and a maximum vibration of 5G.
