As one may expect, the environmental conditions where this module functions can be ridden with all kinds of electrical noise interference and yet these units can operate without having to bother with external isolation transformers.  Without that quality, you would be forced to find another way to transfer electrical power from one source of alternating current power to some other piece of equipment.  No need with the Modicon 140CPS12420C.  Occasionally, your system may be presented with a power loss that is totally unexpected.

What can a power supply module do for you?  It converts the input voltage to managed + 5 VDC for whatever requirements you have for your CPU, the I/O units and whatever communication modules you have installed on the rack.  When you only require low power on your system, you can and should use a standalone power supply module because of it the best choice for you economically. A standalone power supply module is there to provide a 3 A current to your Quantum rack. What supply voltages are you able to use with the standalone power module? They are available for 115/230 V~, 24 V and 125 V ⎓ supply voltages.  On the front panel of the Modicon unit, you will find a model number and also a color code.
