Remanufactured GE-Emerson IC600PM542 Series Six High Capacity I/O Rack Power Supply

The GE-Emerson IC600PM542 Series Six High Capacity I/O Rack Power Supply provides power for Series Six I/O modules, and directly replaces a 115VAC input high capacity I/O power supply should a change in source voltage become necessary or desirable. 

The power supply provides power for high current I/O module configurations and remote (with modem) I/O applications. The input power is applied to a terminal block on the front panel, then routed through a switch and fuse to a switching power supply. For a given load the input power drain is essentially constant. The power supply is protected against polarity reversal of the DC input. 

On the front panel of the I/O rack power supply is an ON/OFF switch labeled LOCG POWER; visible through a lens is an LED indicator that lights when the LOGIC POWER switch is in the ON position, and underneath a black plastic cover is a source voltage terminal block.

The I/O rack power supply also generates a power-fail signal (PSOK) which is used for system initialization and error indications.
