In StockThe Allen-Bradley 1756-PB75R is a Redundant Power Supply module that is used with the 1756 ControlLogix Programmable Automation Controller (PLC) range. This module operates at an input supply voltage range of 18-32 Volts DC with a nominal voltage of 24 Volts DC. It has an output power of 75 Watts @ 0…60 °C (32…140 °F) with a current capacity of 1.5 Amperes @ 1.2 Volts; 4 Amperes @ 3.3 Volts; 13 Amperes @ 5.1 Volts, and 2.8 Amperes @ 24 Volts.
The Allen-Bradley 1756-PB75R ControlLogix Redundant Power Supplies has a power input of 24V DC. The 1756-PB75R provides automatic chassis load sharing between excessive power supplies. This power supply has a status indicator to show the state of the visual operation. The Allen-Bradley 1756-PB75R has an operating temperature of 0-60 °C (32-140 °F). The nonoperating temperature of this unit is -40-85 °C (-40-185 °F). The relative operating humidity of the 1756-PB75R is 5-95% noncondensing. The operational vibration of this power supply is 2 G at 10-500 Hz. The operating shock and the nonoperating shock of this power supply are 30 G and 50 G respectively. The dimensions of the 1756-PB75R are approximately 140 x 112 x 145 mm (5.51 x 4.41 x 5.71 inches). The weight of this power supply is around 0.95 kg (2.10 lb). The Allen-Bradley 1756-PB75R uses the 1756-CPR2 cable to connect the redundant power supply to the 1756-PSCA2 chassis adapter. If you connect or disconnect the 1756-CPR2 cable when the backplane’s power source is on, an electrical arc may occur. This can cause an explosion in a hazardous location. Repeated electrical retractors cause excessive wear on the contacts on the module and on its mating connector. The voltage input connections of this power supply are auto-sensing. You can replace a redundant power supply with another supply while operating the 1756-PB75R in nonredundant mode.
The Allen-Bradley 1756-PB75R is a ControlLogix Redundant power supply. This power supply is specifically used to lower the risk of system downtime due to power supply error as this power supply unit when paired to a redundant partner forms a hot-standby assembly wherein one unit acts as stand-by and one unit acts as active power source. A unit automatically takes over in the event of module error.
The 1756-PB75R operates when supplied with an input voltage range of 18-32 Volts DC, a nominal supply of 24 Volts DC, and a maximum input power of 110 Watts. This power supply has output power of 75 Watts @ 0…60 °C (32…140 °F) and current capacities of 1.5 Amperes @ 1.2 Volts; 4 Amperes @ 3.3 Volts; 13 Amperes @ 5.1 Volts; and 2.8 Amperes @ 24 Volts. This module has an inrush current rating of 30 Amperes, maximum. One major feature of this power supply module is the hold-up time duration of 20 milliseconds.
Additionally, the 1756-PA75R has annunciator power of 90 Volts DC for ATEX/IECEx. It also has an isolation voltage rated 250 Volts (continuous), Reinforced Insulation Type, Power Input to Backplane, Power Input to Annunciator, and Annunciator to Backplane Type tested at 3250 Volts DC for 60 seconds.
The 1756-PA75R redundant power supply is compatible for installation in 1756 chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17. For input supply wiring, applicable cable for use is 2.5 mm2 (14 AWG) solid or stranded copper wire with insulation rating of 90 °C (194 °F), or greater, with maximum insulation thickness of 1.2 millimeters (3/64 inches).
