What You Can Get From Our Different Types of Relays

Safe High-Voltage Operation

Relays allow low-voltage/small-current signals to control high-voltage/large-current loads, eliminating direct high-voltage operation risks and enhancing system safety.

Isolated Circuit Protection

Complete isolation between coil (control side) and contacts (load side) prevents high-voltage interference or damage to low-voltage devices (e.g., PLCs, microcontrollers).

Multi-Circuit Control

Supports NO, NC, and CO contact configurations to simultaneously manage multiple circuits, ideal for complex logic (e.g., motor reversing).

Fast Response

EMR responds in milliseconds; SSR achieves microsecond switching, perfect for high-frequency applications (e.g., PWM dimming, signal routing).

Long Service Life

Optimized contact materials and structures ensure outstanding electrical endurance, reducing maintenance needs and costs.

Safety Protection

Built-in overload/short-circuit protection automatically cuts power during faults, safeguarding equipment and personnel.

Not just a supplier,
but your trusted long-term partner in success.
