The Allen-Bradley 1771-P6R is a redundant power supply module engineered for high-demand PLC environments, operating with an input voltage of 220V AC at 50-60Hz and an input range from 194 to 240V AC. It delivers a reliable output of 5V DC at 8A, backed by a backplane current of 300mA at 5V DC ±5%. Compatible with various I/O chassis models, this module is easily configured through jumpers for remote or local sensing and features I.D. selection switches for assigning unique identifiers in redundant systems. Its design includes parallel connectors for daisy-chaining up to four units to enhance system redundancy, and it is equipped with indicators to monitor redundancy status and operational health.
