Series C75
Optically Isolated 1.0A with Short-Circuit Protection & Trip Status
DC Solid-State Relay
FEATURES/BENEFITS
• Short Circuit Protected:
Prevents damage to system
components, assemblies and
system wiring
• Trip Status: Provides status
monitoring and feedback of the
protection state
• 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
1.0 Adc
• High Dielectric Strength:
For safety and for protection of
control and signal level circuits
DESCRIPTION
The C75-2S solid state relay utilizes
a power FET switch that is protected
against overload and short circuit
currents. Protection is provided
against turn-on into a short circuit,
shorts that occur while conducting
loads up to rated or for long term
overload currents above rated that
slowly overheat the relay. Once the
protection trips the relay off it will
remain off until reset by cycling the
input control. Using the C75-2S to
switch power 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 C75-
2 is packaged in a 16 pin DIP, with
surface mount or through hole
mounting available. The C75-2SH
also provides an open collector trip
status feedback to the relay’s control
side for short circuit and thermal trip
monitoring.
H = Relay has an internal over
voltage suppressor for
inductive loads.
