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.

An optional plastic safety cover can be installed on a Power Series SSR.

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, 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).

DIN-rail adapter is included.

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.
