About 1734-OB8
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.
