Toshiba Starts Shipment of UL 508 Certified Photorelays for Industrial Control Equipment

May 22, 2019

Toshiba Electronic Devices & Storage Corporation

DIP4

TOKYO— Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has obtained US safety standard UL 508 certification for the following nine photorelay products: DIP4 package series “TLP3556A,” “TLP3558A” and “TLP241A;” and DIP6 package series “TLP3543A,” “TLP3545A” and “TLP3546A;” and DIP8 package series “TLP3547,” “TLP3548” and “TLP3549.”

 

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[1] 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) [2]. 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.

Applications

  • Industrial equipment (PLC, I/O interface, various sensor control, etc.)
  • Building automation systems (heating, ventilation, and air conditioning (HVAC), thermostat, etc.)
  • Replacement of mechanical relays(AC24 to 400V system, DC24 to 125V system)

Features

  • UL 508 (NRNT) approved
  • UL 1577 approved
  • Case temperature (Max): Tc=105℃
