Power Series SSR Accessories
Safety Cover
A plastic safety cover (Opto 22 part number SAFETY COVER) is
available for use with Opto 22 Power Series SSRs. The safety
cover reduces the chance of accidental contact with relay
terminals, while providing access holes for test
instrumentation.
SSR-HS Heatsink
Custom designed for the Power Series SSRs, the SSR-HS
heatsink provides excellent heat dissipation when mounted to
the SSR with a matching thermal conductive pad, which is
used in place of silicon grease. One thermal pad is included
with the heatsink. Additional pads may be purchased in packs
of 10 (part number SSR-THERMOPAD).
Thermal Ratings
The thermal ratings shown in the following graphs were
obtained with an SSR attached to a heatsink using a thermal
conductive pad.

Heatsink Assembly
Before attaching the SSR, remove the protective film from
both sides of the thermal pad, then place the pad on the
heatsink making sure to align the holes. Secure the SSR to the
heatsink with the two 8-32 x 3/8˝ panhead Phillips screws
included in the kit. Use 20 in-lb (2.26 N-m) of torque.
NOTE: To take advantage of the
cooling effect of natural air flow,
mount the SSR/heatsink assembly to
a vertical surface with the Opto 22
logo right side up as shown here.
