PLC

Programmable Logic Controllers (PLCs) serve as the central nervous system of industrial automation, coordinating complex logic, I/O processing and communication among sensors, actuators and higher-level control systems. In power grids with frequent voltage dips, surge events and high-frequency interference from drives and inverters, PLCs face threats from transient surges, electrostatic discharge (ESD) and conducted electromagnetic interference (EMI). YINT Electronics’ PLC protection solution integrates high-energy gas discharge tubes (GDTs) to divert surge energy, MOV surge protectors for energy absorption on power lines, TVS transient suppressors for fast overvoltage clamping, ultra-low capacitance ESD protection arrays to protect sensitive data/signal lines, and EMI filtering components to suppress conducted noise. These layered protections ensure reliable, zero-downtime operation under harsh industrial electrical environments.
