C75 1

C75\112004\Q1

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.
