The Allen-Bradley 1771-P4S is a PLC 5 automation platform power supply. This module is a single-slot module that is used to deliver power to the backplane which is used by any Allen-Bradley 1771 modules to operate their individual circuitries.
The 1771-P4S is compatible for use with 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B Universal I/O Chassis. It operates when provided with an input supply range of 92-132VAC along an input frequency range of 47-63 Hz while the module’s nominal input supply voltage is 120VAC. This power supply module is capable of providing an output voltage of 5VDC and output current of 8 Amperes. This module supports operation along another Power supply connected in parallel using the Parallel cable connector. This connection increases the power being delivered to the backplane, enabling more modules to be operated without the need of partitioning to another rack.
