The 1756-PBXT is a ControlLogix XT Power Supply manufactured by Allen-Bradley. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply is part of ControlLogix-XT Power Supply Series. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply features 18 to 32 Volts DC input power, 4 Volts at 8 Amps output, extended temperature conformal coating, 24 Volts DC input voltage, 81W input power, 52W power output, and 250 Volts constant isolation voltage. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply has no enclosure rating (Open Style). The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply consist of control and communication system components which are utilized with the controller Flex I/O-XT™ components. The dimensions of the Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply is 14.0 x 11.2 x 14.5 centimeters, and the weight is 0.95 kilograms. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply is configured with current capacity of 10 Amps at 5.1 Volts. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply offers a scalable controller solution which is capable of addressing a large number of I/O points. The ControlLogix-XT Power Supply can be placed into any slot of a ControlLogix-XT and installed with other multiple controllers on one chassis.
When the Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply is connected with other controllers on one chassis, the ControlLogix-XT Power Supply communicates with each controller over the backplane chassis, but the Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply operates independently. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply has an operating temperature range of -25 to 70 degrees Celsius, a non-operating temperature range of -40 to 85 degrees Celsius, a maximum surrounding air temperature of 70 degrees Celsius, a relative humidity of 5 to 95%, non-condensing, an operational vibration of 2G at 10 to 500 Hertz, an operating shock 30G and a non-operating shock of 50G. The Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply has IEC 61000-6-4 rated emissions, ±KV line-to-line (DM) and ±2 KV line-to-earth (CM) on the power ports for surge transient immunity. Mount the Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply on the left side of the 1756 chassis. The users should keep the wire distance as short as possible to minimize the resistance between the 1756 chassis and the ground connections. When installing the Allen-Bradley 1756-PBXT ControlLogix-XT Power Supply, it is advisable to leave 6-inch gap between the 1756 chassis and the heat source, and the user should leave a 2-inch gap between the wire-way and either the top or bottom of the 1756 chassis.
