| Öğe açıklaması | Isolated safety barriers / the analog input isolated safety barrier provides isolated power supply for two- and three-wire transmitters in hazardous areas. The 4~20MA signal generated by the transmitter or current source is transmitted from the hazardous area to the safe area output, thereby driving the load in the safe area. For two- and three-wire transmitters or current source signals, the safety barrier supports two-way communication of HART digital signals superimposed on the 4~20MA signal, and has a disconnection alarm function. This product needs to be independently powered, and the power supply, input, and output terminals are isolated |
