SR75-2 1
SR75-2\062004\Q1
0.75A, 300Vdc Optically Isolated, Short-Circuit Protected
for AC or DC Loads DC Solid-State Relay
FEATURES/BENEFITS
Short-Circuit Protected
: Prevents
damage to system components,
assemblies and system wiring. Can
be connected to protect AC or DC
loads (AC with diode bridge)
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 Voltages
: To 300 Vdc
Switches High Currents
: To 0.75 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 SR75-2 solid-state relay utilizes a
power FET switch that is protected
against
overload
and
short-circuit
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. Once the protection trips
the relay, it will remain off until reset by
cycling the input control line. Using the
SR75-2 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 SR75-2 is packaged in
a 16-pin DIP package with either
surface-mount or through-hole mounting
available.
