These certified photorelays, all commercially available, can be used in industrial control equipment that requires UL 508 certification, suiting them for use in a wider range of equipment marketed worldwide. These photorelays are also NRNT certified.

The UL 508 standard includes stringent standards for parts. Solid state relays (SSR) are one such category of parts, and the resin temperature within an SSR is restricted to 105 ºC (upper limit). SSRs can be operated at temperatures up to the upper limit.

By using Toshiba UL certified products, users can manufacture control equipment compliant with the UL standard and maintain the thermal design margin required for SSRs.
