1734-OB2E

The Allen-Bradley 1734-OB2E is a 24V DC 1734 POINT I/O source output module with 2 channel enhanced source outputs that are non-isolated. It has a maximum output current rating of 2A, with 1A per output. The on-state voltage of this module is a minimum of 10V DC, a maximum of 28.8V DC, and a nominal 24V DC. The maximum on-state voltage drop is 0.2V DC and minimum on-state current per channel is 1 mA. The 1734-OB2E’s maximum off-state voltage is 28.8V DC and the maximum off-state leakage is 0.5 mA. This drive also has a surge current of 2A for 10 ms that is repeatable every 3s. The maximum power dissipation is 0.8 W and the maximum thermal dissipation is 2.7 BTU/hr, both at 28.8V DC. The 1734-OB2E’s continuous isolation voltage is 50V and is a reinforced insulation type that has been tested field-side to the system at 2500V DC for 60s. This module has an external DC power voltage range of 10-28.8V DC, nominal external DC power supply of 24V DC, and external DC power supply current of 8 mA. The maximum signal delays of the 1734-OB2E output module are both 0.1 from off-to-on and from on-to-off. Note that this module’S maximum POINTBus current IS 75 mA at 5V DC. Red/green/yellow status indicators are present in this module and it has a key switch position of 1. The 1734-OB2E has an open-type enclosure rating and can be installed to a 1734-TB or 1734-TBS wiring base assembly. The operating temperature is -20-55 ËšC and the non-operating temperature is -40-85 ËšC. The entire 1734-OB2E module measures 2.21 x 0.47 x 2.97 inches. This output module is electronically protected.
