Operating Diagram Heatsink Recommendations
We recommend that solid state relay modules be mounted to a
+ A1
heatsink sufficient to maintain the modules base temperature at less
ZERO
Control A
VOLTAGE Output A
than 85C under worst case ambient temperature and load conditions.
VDC Input
CIRCUIT
The heatsink mounting surface should be a smooth (30-40 micro-inch
A2
finish), flat (30-40 micro-inch flatness across mating area), un-painted
+ B1
surface which is clean and free of oxidation.
ZERO
Control B
VOLTAGE Output B
VDC Input An even coating of thermal compound (Dow Corning DC340 or
CIRCUIT
equivalent) should be applied to both the heatsink and module mounting
B2
surfaces and spread to a uniform depth of .002 to eliminate all air
pockets.
Random Turn-on Units have a Random Turn-on circuit instead of Zero Voltage Circuit
The module should be mounted to the heatsink using two #10 screws.
