A PLC power supply is the workhorse of the PLC system. It converts your line voltage, 120 or 240 volts AC, to a lower DC voltage, commonly 24 volts DC. This DC voltage is then sent into the rack to power the rest of the PLC components.
In such cases we must have a power supply that converts 230VAC to 24VDC. How to choose the right power supply? To answer this question, we will build our own PLC + HMI set, calculate the power consumption and select the appropriate power supply. Let''s do it!
The comprehensive SITOP power supply portfolio offers controlled 24 V DC power supplies for a wide range of industrial applications and requirements.
In standard, PLC operates in four types of voltages – 24V DC, 24V AC, 110V AC, and 240V AC. In some PLCs, only the CPU requires a power supply and the IO modules get supply from the CPU backplane, whereas in some PLCs, all the modules including CPU, inputs, and outputs require a power supply.

The source for a PLC power supply is generally single-phase and 120 or 240 VAC. If the controller is installed in an enclosure, the two power leads (L1 hot and L2 common) normally enter the enclosure through the top part of the cabinet to minimize interference with other control lines.
