Allen-Bradley 1771-A3B1 Universal 12-slot l/o chassis

Allen-Bradley 1771-A3B1 Universal 12-slot l/o chassis

Description

The 1771-PSC Power Supply chassis provides 4 slots for mounting modular power supplies to provide up to 24 amps to a 1771 Universal I/O chassis. It can also be used to mount communication modules that need only +5V DC power and a processor enable signal. The 1771-PSC may be mounted either directly to a 1771-A1B, A2B, A3B1, or A4B (series B) Universal I/O chassis, or mounted separately

The 1771-PSC Power Supply chassis accommodates a variety of Allen-Bradley power supplies and communication modules. The number and type of power supplies used determines the number of slots available for communication modules.

Each enclosure must contain a central ground bus. The ground bus is the common connection for each chassis within the enclosure and the enclosure itself. Use either bolts or welded studs to mount the I/O chassis and central ground bus. If you are mounting a chassis to the back panel of an enclosure, use 1/4-20 (M6 x 10) mounting bolts.
