The Allen Bradley 1756-PBXTR is a ControlLogix-XT redundant power supply that includes control and communication system components that can be used with FLEX I/O-XT ™ products. It measures approximately 17.5 x 14.5 x 13.7 cm (6.9 x 5.7 x 5.4 in) and weighs approximately 1.45 kg (3.2 lb). It has a current capacity of 5.1A at 10 volts.
This power supply is installed on the left side of the 1756 chassis; When installing the 1756-PBXTR, keep the wire length as short as possible to minimize resistance between the chassis and the ground connection. Leave 15.3 cm (6.0 in) between the chassis and the heat source, and 5.1 cm (2 in) between the wire slot and the top or bottom of the chassis. The chassis can only be installed horizontally. Do not install the chassis vertically.
The 1756-PBXTR operates at temperatures of -25 to 70 degrees Celsius (-13 to 158 degrees Fahrenheit); During storage, the device can maintain temperatures between -40 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit). The maximum ambient air temperature of this power supply is 70 degrees Celsius (158 degrees Fahrenheit). Its relative humidity is based on IEC 60068-2-30 of 5% to 95%, without condensation.
