MTL4728– FOR NEGATIVE AND FLOATING SUPPLIES – for switches, solenoids, LEDs, 4/20mA, transmitters, etc
The MTL4728– is a 4-channel barrier designed to be used in applications using negative or floating power supplies and positive
earths. It is identical to the MTL4728+ barrier except that the safety diodes are reversed. It can also be thought of as an MTL4706+
without the built-in power supply. Used with a floating supply, it provides a positive output wrt 0V to the safe area.
