The full form of PS in PLC (Programmable Logic Controller) stands for Power Supply.
The power supply is a crucial module within a PLC system. It provides the necessary voltage to power the PLC's CPU (Central Processing Unit) and other modules. Most PLC systems operate on 24V DC voltage. The power supply converts typical line voltage, such as 100-240 VAC, into the lower DC voltage required for the PLC's operation, typically 24 VDC. Therefore, a stable and reliable power supply is essential for the proper functioning of the PLC. Without it, the PLC cannot operate.
