👉 PLC (Programmable Logic Controller) fluid, often referred to as hydraulic fluid, is a thick, viscous liquid used in PLC systems to transmit signals and control operations. It acts as a medium for the physical movement of internal components, such as valves and motors, which are essential for the PLC's control functions. This fluid ensures smooth and precise operation by reducing friction and wear, while also dissipating heat generated during the control processes. Proper maintenance of the PLC fluid is crucial for the longevity and reliability of the system, as contamination or degradation can lead to malfunctions and reduced performance.
