SR75-1 1
SR75-1\062004\Q1
1.5A, 60Vdc Optically Isolated, Short-Circuit Protected
DC Solid-State Relay
FEATURES/BENEFITS
Short-Circuit Protected: Prevents
damage to system components,
assemblies and system wiring
Optical Isolation: Isolates control
circuits from load transients
Eliminates ground loops and signal
ground noise
Low Off-State Leakage: For high off-
state impedance
Switches High Currents: To 1.5 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 SR75-1 solid-state relay utilizes a
power FET switch that is protected
against
short-circuit
and
overload
currents. The short-circuit protection
feature not only provides protection
should a short or overload occur while
the relay is on, but will also provide
protection should the relay be 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 SR75-1 to
switch power sources and loads can
prevent
fires,
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 SR75-1 is packaged in a 16-pin
DIP package with either surface-mount
or through-hole mounting available.
