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.
