Introduction to Relays

Introduction to Relays

Relays are electrical control devices used to automatically turn on or off circuits. They play a crucial role in controlling, protecting, and regulating electrical systems. The company specializes in producing various relays, such as time relays, solid-state relays, intermediate relays, RXM relays, RM control relays, liquid level relays, and phase sequence relays. These relays are designed with high-quality standards, strictly controlled in production, and continuously improved in the quality management system. The company has introduced international advanced production and testing equipment and is the first in the domestic electrical appliance industry to pass ISO - 9001 quality system certification and International Electrotechnical Commission IECO certification.

Advantages

High-Quality Manufacturing and Strict Quality Control

The company ensures high-quality relay production through strict quality control, regarding quality as the lifeline of the enterprise. It continuously improves the quality management system and introduces international advanced production and testing equipment, ensuring each relay meets rigorous standards. The relays have passed ISO-9001 quality system certification and International Electrotechnical Commission IECO certification, demonstrating reliable quality and international recognition.

Advanced Technology and Long Service Life

Solid-state relays adopt semiconductor devices for contactless control, featuring fast switching speed, long service life, and strong anti-interference ability. Compared with traditional mechanical relays, they have no mechanical wear, reduce maintenance costs, and are suitable for high-frequency operation scenarios. Other relays like intermediate relays also use advanced design concepts to ensure stable performance and prolonged service life, providing reliable long-term use for users.

Precise Control and Signal Conversion Capability

Intermediate relays play a key role in control circuits by amplifying signals, increasing the number of contacts, and realizing signal conversion, enabling precise control of other electrical equipment. Phase sequence relays can accurately detect the phase sequence of three-phase power supplies and promptly issue signals or cut off circuits when phase sequence errors or phase loss occur, effectively protecting equipment safety. These functions make relays critical components for ensuring the accuracy and stability of electrical systems.

Related products

Miniature relays are compact devices measuring from 15 to 25 mm in width. They have medium-duty application capabilities, striking the balance between size and performance. Unlike micro relays, miniature relays have coil voltage and contact ratings reaching 30 Amps. Their voltages are compatible with low-voltage logic (5V DC) and industrial control (24V DC) systems. Common types include power miniature relays (SPST/SPDT) and latching variants for memory functions. Their rugged enclosures and plug-in bases make them perfects for robotics, medical devices, and renewable energy inverters while meeting UL 508 and CE standards.
