MTL7991 power feed module MTL safety barrier for sale!
MTL7991 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.
