Series FR75-1
1.0A, 60 Vdc Optically Isolated
Short-Circuit Protected
FEATURES/BENEFITS
• Short-circuit protected: Prevents damage to
system components, assemblies and system
wiring
• Optical isolation: Isolates control circuits from
load transients and eliminates ground loops and
signal ground noise
• Low off-state leakage: For high off-state
impedance
• Switches high currents: To 1.0 Adc
• High noise immunity: Control signals isolated
from switching noise
• High dielectric strength: For safety and for
protection of control and signal level circuits
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.
