Product catalog summary
Overview: The document provides technical specifications for the Series SQ Quad Output 25A, 280 Vac DC Solid-State Relay by Teledyne Relays. It includes details on part numbers, electrical and mechanical specifications, features, and typical applications.
Part Numbers: The series includes models SQ24D25, SQ24R25, and SQ24R25-02, all rated at 25A, 240 Vac.
Electrical Specifications:
  • Input (Control): Control voltage ranges from 3-32 Vdc for SQ24D25 and 4-40 Vdc for SQ24R25. Typical turn-on voltage is 4.3 Vdc, with a must turn-off voltage of 1 Vdc.
  • Output (Load): Operating range is 12-280 Vrms with a peak voltage of 600 Vpeak. Load current ranges from 0.005 to 25 Arms. Maximum surge current is 240 A, with an on-state voltage drop of 1.2 V.
Features/Benefits: The relay offers four independently controlled solid-state relays, tight zero-cross window for low EMI, constant current input, and optical isolation for protection. It is suitable for heating, motor control, and industrial applications. UL recognized.
Mechanical Specifications: The relay weighs 3.175 oz (90g) and includes Faston terminals for connectivity.
Environmental Specifications: Operating and storage temperatures range from -40 to +100°C. Input-output isolation is rated at 4000 Vrms.
Optional Add-Ons: Thermal pad installation is available as an add-on.
