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

The Key Features of the Photorelays include:

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

The Major Applications of the device include:

  • 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)
