The LYA-R series thermocouple isolation safety barrier primarily serves to receive thermocouple signals from hazardous areas on-site, isolates and converts them, and then transmits the signals to control systems or other combined instruments located in safe areas. It prevents hazardous signals from entering the hazardous environment via the intrinsically safe terminals, while also ensuring electrical, input, and output circuits remain completely isolated from one another.
The LYA-R series thermocouple isolation safety barrier primarily serves to receive thermocouple signals from hazardous areas on-site, isolates and converts them, and then transmits the signals to control systems or other combined instruments located in safe areas. It prevents hazardous signals from leaking back into the hazardous area via the intrinsically safe terminals, while also ensuring complete electrical isolation among the power supply, input, and output circuits.
The LYA-C series operator-isolated safety barrier primarily functions by receiving the 4–20mA signal from controllers or operators located in the safe area, isolating and converting it before outputting, thereby driving field-mounted actuators. It also prevents hazardous signals from entering the potentially explosive environment via the intrinsically safe terminals, while ensuring complete electrical isolation among the power supply, input, and output circuits.
Suitable for situations where it is inconvenient to provide separate power on-site, requiring isolation of on-site equipment and systems to enhance the system's resistance to interference. <p> Application 1: Receive the current signal output from the four-wire transmitter on-site, isolate it, and then output it to the system; <p> Application 2: Alternatively, receive the current signal output by the system, isolate it, and then send it to the field-mounted valve positioner or electrical converter. <p> In both application modes, the energy consumption during operation comes entirely from the input circuit. </p></p></p>
