| Descripción del artículo | Isolated safety barriers / "the surge protection analog input isolated safety gate provides isolated power supply for the two or three wire transmitter or current source signal in the dangerous area, and the 4~20MA signal generated by the transmitter or current source is transmitted from the dangerous area to the safe area output, thereby driving the load in the safe area." for two-wire transmitters or current source signals, the safety grid supports bidirectional communication of HART digital signals superimposed on 4~20MA signals, and has a disconnection alarm function.the product needs to be independently powered, and the power supply, input and output are isolated." |
