MTL7991 isolators for power feed module.

The MTL7991 power feed module incorporates both voltage and current sense mechanisms to protect barrier circuits by activating a

solid-state trip mechanism when fault or overload conditions occur in the power source circuit. Resetting the module after tripping is done by interrupting the supply to the unit. A red LED indicates a circuit trip condition and a green LED the availability of power at the outputs.
