Product Description
Product Overview Product overview
The LYA-C series isolation safety barrier primarily serves to receive the 4–20 mA signal from controllers or operators located in the safe area, isolating and converting it before outputting, thereby driving field actuators. It also prevents hazardous signals from entering the hazardous area via the intrinsically safe terminals, while ensuring complete electrical isolation among the power supply, input, and output circuits.
