42F Interface Relay
- Input: 3–32 VDC; Output: 5–60 VDC
- Semiconductor-controlled for noise-free switching.
- Ideal for space-sensitive and high-density installations.
- No mechanical contacts or arcing, ensuring long service life
- Compatible with ESP32 and Raspberry Pi development boards.
- Low power consumption and high surge capability.
Product Overview & Applications:
Solid State Relay (SSR) products utilize SCRs or MOSFETs to achieve precise and rapid control over loads. The control circuitry is optically coupled and isolated from the load, offering high dielectric strength to provide protective isolation for upstream control components.
Solid-state relays have gained widespread adoption and application across various fields, including hazardous and explosion-proof environments, lighting control systems, electromechanical automation control, and medical equipment.
