‌SKJ-C Electronic Speed Relay Product Introduction (English Version)‌

The SKJ-C Electronic Speed Relay is a high-performance monitoring device designed for industrial equipment and automated control systems. It delivers precise speed monitoring and protection solutions for motors, transmission systems, and rotating machinery. By capturing real-time rotational speed signals, it intelligently assesses operational status and triggers control commands to prevent equipment damage or safety hazards caused by overspeed, underspeed, or unexpected stoppages, thereby enhancing production continuity and extending asset lifespan.

Utilizing advanced signal processing technology, the relay ensures stable speed signal detection even in complex working environments, with millisecond-level response times for instantaneous feedback on abnormal conditions. Its multi-stage sensitivity adjustment module allows users to flexibly configure activation thresholds based on specific equipment characteristics, making it adaptable to diverse scenarios ranging from low-speed precision instruments to high-speed power systems. The circuit design incorporates anti-interference optimization to minimize the impact of electromagnetic noise and voltage fluctuations, ensuring reliable data acquisition.

Practicality and user-friendliness are central to the SKJ-C’s design. Its compact structure enables seamless integration into control cabinets, offering both DIN rail and screw mounting options. Universal interfaces support multiple input modes, including pulse signals and analog voltage, ensuring compatibility with mainstream sensors and PLC systems. An intuitive LED status indicator and external reset function streamline debugging and troubleshooting processes. Additionally, low-power components reduce operational heat generation, enhancing long-term durability.

This relay finds extensive application in elevator safety controls, crane speed limiting systems, fan-pump linkage mechanisms, and conveyor line equipment, particularly in industries such as mining, power generation, and metallurgy where operational reliability is critical. By providing real-time speed protection and equipment health alerts, the SKJ-C helps enterprises mitigate unplanned downtime risks and optimize maintenance efficiency.
