Industrial PLC control board revolutionizes automated system management by integrating precision isolation control with flexible power distribution, ideal for manufacturing lines, energy plants, and smart factory applications. The core design emphasizes 6 channels of PLC isolation control, each equipped with high-voltage optocoupler isolation (2500Vrms) to prevent electromagnetic interference (Emi) and ground loops—critical for maintaining signal integrity in noisy industrial settings. Each channel supports both NPN/PNP input signals and relay/output switching, accommodating a wide range of sensors, actuators, and control devices.
