DESCRIPTION

The FR75-1 solid-state relay utilizes a power FET

switch that is protected against short circuits and

overload currents. The short-circuit protection feature

provides protection when a short or overload occurs

while the relay is on as well as when the relay is

switched into a short. In either case, the relay will

sense the short-circuit condition and then block it

indefinitely until the short is removed and the unit is

reset by cycling the input control. Using the FR75-1

to switch power sources and loads prevents damage

to system assemblies and system wiring. The power

FET output offers low “ON” resistance and can switch

loads in either the high or the low side of the power

line. The FR75-1 is packaged in a low-profile mini-

DIP package.
