The 1734-OB2EP is an Allen-Bradley module which has 2 non-isolated sourcing outputs. It has an input voltage that ranges from 10 to 28.8 Volts DC. The output current rating at its greatest is 4.0 Amps per module and 2.0 per channel and the point bus current is 75 mA at 5 Volts DC.

Its peak power dissipation is 3.4W at 28.8 Volts DC and the terminal base unit is the 1734-TB or the 1734-TBS wiring base assembly. The model’s thermal dissipation is at 11.6 BTU/hour at its peak on 28.8 Volts DC. The 1734-OB2EP’s isolation voltage is 50 Volts continuous tested at 1250 Volts AC for 60 seconds.

The ON-state voltage drop is 0.7 Volts DC at 28.8 Volts DC and 55 degrees Celsius in the full load condition. The output signal delay for both OFF-ON and ON-OFF is 0.1 milliseconds at its peak. The 1734-OB2EP has at its greatest OFF-State leakage of 0.5 mA. It also comes with an ON-state current of 1.0mA per channel.

The 1734-OB2EP’s operating shock is 30g at peak acceleration and the non-operating shock is 50g at peak acceleration. It has a relative humidity of 5 to 95% non-condensing and operational temperature of -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit). The storage temperature is -40 to 85 degrees Celsius. Its default data map has a message size of 1 byte.

The wiring output modules have a connection from 0 to 3, common terminal for 4 and 5, and Supply/Power for 6 and 7. Where V = 12/ 24 Volts DC. It comes with several indicator lights; 2 yellow for output status, 2 red for output faults, and 2 green/red for module/network status. It has 1 key switch position. Overall, the 1734-OB2EP has dimensions of 2.21 x 0.47 x 2.97 inches. It has a mass of 1.15 ounces/32.60 grams and a terminal base screw torque of 7 pounds-inches.
