A: Single relay or with 0.75” spacing between relays. Derate above 40 °C; subtract 0.5 amp/°C.
B: Three relays side by side with 0.25” spacing. All relays with the same load. Derate above 40 °C; subtract 0.4 amp/°C.
NOTE: This data is for SSRs mounted to a horizontal surface. To take advantage
of the cooling effect of natural air flow, we recommend mounting HS-series SSRs
to a vertical surface with the Opto 22 logo right side up as shown here.
