The Allen-Bradley 1771-PSC is a Power Supply Chassis with 4 slots, designed for PLC-5 systems. This item provides electrical power through a direct connection or through a cable connection to a Rockwell Automation I/O chassis. This PLC-5 power supply chassis houses 4 slots and it can encapsulate 4 modular power supplies. It can withstand maximum backplane current of 20 Amps at 60 degrees Celsius and 24 Amps at 55 degrees Celsius. The specific feature of this chassis is that it accepts communication modules to be mounted inside of it. This only stands for communication modules that work with 5 Volts DC power and a processor enable signal. It can connect to a 1771-A1B, 1771-A2B, 1771-A3B1, or 1771-A4B (series B) universal I/O chassis. The user should be aware that the total power supplies in 1771 I/O chassis must not exceed the 24 Amps limit. Take this into consideration configuring power supply modules to place in the 1771-PSC chassis.
The 1771-PSC housing has dimensions of 311 millimeters x 203 millimeters x 180 millimeters (12.23 inches x 8.0 inches x 7.1 inches). Approximate weight of the module is 1.9 kilograms (4.1 pounds). When it comes to mounting, this device is a back-panel mountable. Mounting holes distances are 7 inches (178 millimeters) horizontally and 10 inches (254 millimeters) vertically. This power supply chassis operates at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) temperatures. It can be stored at -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit) temperatures. The power supplies or communication modules installed in this chassis are cooled by convection air flow.
