The Allen-Bradley/Rockwell Automation 1756-PA75R is a Redundant AC Power Supply module from the ControlLogix line of products. The panel-mount module comes with a chassis from Series B, which is automated and has the ability to share loads between power supplies that produce excessive amounts of power. Despite this ability, this power supply system is engineered to resolve operational faults in the power supply only. The dimensions (height x weight x depth) of the module are approximately 17.5 x 14.5 x 13.7 centimeters (6.9 x 5.7 x 5.4 inches), and it weighs around 1.45 kilograms (3.2 pounds). The module requires 120 to 220 Volts AC power input, and its input frequency is 47 to 63 Hertz. The isolation voltage of 1756-PA75R is 250 Volts continuous, and the power output it produces is 75 Watts at 60 degrees Celsius. The status of operation of the system can be monitored by status indicators, while the supply status can be monitored using the system recognition relay.
Both the annunciator and conductor of 1756-PA75R are made of a copper wire, solid or stranded, with the annunciator having a Category 3 wire, and the conductor a Category 1 wire. The conductor wire is 2.5 square millimeters (14 AWG) rated at 90 degrees Celsius (194 degrees Fahrenheit), and it has a maximum insulation of 1.2 millimeters (0.047 inches). The annunciator wire can be thinner, and it may range between 0.25 and 2.5 square millimeters (22 to 14 AWG) rated at 90 degrees Celsius (194 degrees Fahrenheit). The annunciator is not rated in terms of duty rating, and the conductor screw torque amounts to 0.79 N-m (7 pounds per inch). This module is highly durable, and it can withstand temperatures as high as 60 degrees Celsius (140 degrees Fahrenheit). The IEC / CISPR Publications 11 state that this module is Class 1, Class A Appliance. However, the user needs to bear in mind that radiation and disruption may cause difficulties in achieving electromagnetic compatibility.

About 1756-PA75R
The 1756-PA75R power supply is a redundant power supply that has been designed by Allen-Bradley and that has been designed to be exclusively used with the ControlLogix controllers. Additionally, this power supply has been included in the accessories catalog for the ControlLogix systems. The main function of this redundant power supply system is to provide additional uptime power and protection for each chassis that is used in critical applications. It has been designed to share the current that is required by the chassis and it operates with AC voltage. The Allen-Bradley 1756-PA75R redundant power supply is made to be installled in a pair with another similar power supply so that in case one power supply fails, the other one will provide power to the chassis and avoid any disruptions that can cause machine damage or data loss.
The Allen-Bradley 1756-PA75R redundant power supply does not come with any special protective features. This power supply comes with line power and with a protective earth connection that is meant to be attached to the chassis ground lug or a ground bus. The Allen-Bradley 1756-PA75R redundant power supply operates with a voltage range of 120 to 240 Volts AC, a frequency range of 50 to 60 Hertz, and a power consumption rating of 115 Watts. It also provides a continuous insulation voltage of 250 Volts. The power supply does not include an enclosure and it can work in a temperature range of 0 to 60 degrees Celsius. Once connected to the chassis, the power supply needs to be included in the grounding system. A solid-state relay can be connected to this power supply to ensure that it is working properly.
The Allen-Bradley 1756-PA75R redundant power supply has a voltage range of 120 to 240 Volts AC and a frequency range of 50 to 60 Hertz. It is manufactured as part of the ControlLogix series.
