4.1 Power Supply Module
A power supply module is connected to a 100 to 120 V AC or 220 to 240 V AC or 24 V DC
main source and supplies insulated +5 V and +24 V to each installed I/O module through the
back board.
The +5 V and +24 V outputs support dual-redundant insulated output operation.
Power supply modules available to ProSafe-RS: SPW481 (100-120 V AC), SPW482 (220-240
V AC), SPW484 (24 V DC)
