A UPS ensures continuous operation of PLCs by providing a seamless transition to backup power during power outages or disturbances. The UPS can be used for two purposes. Feeding the power supply of the PLC or feeding the power supply for the control circuits that are wired to the I/O cards of the PLC.
Uninterruptible Power Supplies (UPS) come into play as a safeguard against power disruptions that could compromise the functionality and reliability of PLCs. What Is a PLC? A Programmable Logic Controller (PLC) is an industrial computer specifically designed for controlling and automating manufacturing processes.
PLCs normally use power supplies that convert a line voltage, like 120 V or 240 V AC, into a DC voltage. The DC power supply, commonly 24 V, is used to power all of the components plugged into the backplane or rack of the PLC. Isolation is necessary in PLC I/O module power supplies to protect equipment and humans from high voltage surges.
The output of the Power supply is a DC voltage used to power all of the other modules associated with the PLC. Usually, the input power of the PLC system is 120V/240V AC, and the output power is 24V DC. This DC voltage is then sent into the rack to power the rest of the PLC components. The Power supply DOES NOT provide power for field devices.
