Product Description
Product Overview Product overview
The LYA-J series isolation safety barrier primarily serves to provide isolated intrinsically safe power voltage to transmitters located in hazardous areas. It isolates and converts the 4–20mA signals generated by the transmitters, then transmits them to the control system or other combined instruments in a safe area. Additionally, it prevents hazardous signals from leaking into the hazardous environment via the intrinsically safe terminals, while ensuring electrical isolation among the power supply, input, and output circuits.
