MTL5040 LOOP ISOLATOR two channel 4/20 mA With Good Price In Ready Ship
MTL5040 provides a fully floating dc supply for energising a conventional 2-wire 4/20mA transmitter located in a hazardous-area and repeats the current in another floating circuit to drive a safe-area load. It also passes on a 4/20mA or 0/20mA signal from a controller
located in the safe-area to a load in the hazardous-area.Hazardous area Safe area
