About 1734-OB8

The Allen-Bradley 1734-OB8 is part of the 1734 Point I/O product family. This module is an Eight (8) channel discrete output module that is used to energize electrical loads such as relays, pilot lamps, solenoid actuated devices and other devices that operated at a voltage range of 10-28.8 VDC. It is used to actuate Final Control Elements (FCE) to execute manual or automatic commands, according to the downloaded user program in the controller’s memory.

The 1734-OB8 is a small, compact sized output module that support DIN rail mounting. It requires minimum mounting space as it come with physical dimension of 56.0 x 12.0 x 75.5 mm (2.21 x 0.47 x 2.97 in.). It can be attached to any adjacent POINT I/O module or an POINT I/O communication adapter. The limit to the number of instances of 1734-OB8 is based on the controller’s memory capacity and the allowed number of POINT I/O nodes a specific communication protocol and adapter supports.

The 1734-OB8 cannot operated as a standalone device. It requires a POINT I/O communication adapter that manages the bi-directional transfer of between the controller and the POINT I/O module. Additionally, the 1734-OB8 is bus powered. It draws power from the POINT I/O bus with a rated current draw of 75 mA. To establish connections to this module, it requires use of 1734-TB or 1734-TBS wiring base assembly.

The 1734-OB8 has an output current rating of 1.0 A per output, not to exceed 3.0 A, maximum per module. It has minimum ON-state voltage of 10VDC and maximum ON state voltage is 28.8VDC.

The 1734-OB8 has a surge current rating of 2 Amps for 10 milliseconds that is repeatable for 3 seconds. It comes with 8 yellow indicator lights for the output status and 2 green/red for the module/network status. The 1734-OB8 has a thermal dissipation of 6.8BTU/hour. The product's isolation voltage is 50 Volts continuous tested at 2500 Volts DC for 60 seconds. The 1734-OB8’s external DC power supply is 32mA with an approximate dimension of 56.0 x 12.0 x 75.5 millimeters with a wiring category of 2 ON-signal ports. The Allen-Bradley 1734-OB8 has an operating temperature of -25 to 55 degrees Celsius and a non-operating temperature of -40 to 85 degrees Celsius. Its operating shock is 30G and its non-operating shock of 50G. Its vibration is 5G at 10 to 500 Hertz and relative humidity of 5 to 95%, non-condensing.
