High-Voltage Voltage-Detection Device

The high-voltage live display interlock device provides a direct visual indication of whether electrical equipment is energized. When the equipment is energized, the indicator flashes automatically, alerting operators in real time. This device can work together with electromagnetic locks, mechanical program locks, and microcomputer-based anti-misoperation interlock devices. Through enforced interlocking, it effectively prevents electrical misoperation risks. Some models integrate additional functions such as phase checking, circuit self-test, on-site calibration, and operating status display. Certain outdoor series also provide real-time voltage display, mode setting, fault interlock, and undervoltage interlock, meeting diverse application requirements.

Remote Interlock Device

The remote interlock system consists of the microcomputer anti-misoperation interlock host, remote interlock controller, and remote interlock relay. The microcomputer anti-misoperation interlock host serves as the core control unit, issuing remote operation commands, while the remote interlock controller and relay work together to form the remote interlock device. By connecting the normally open contact of the remote interlock relay in series with the remote/local control circuit, the system creates a physical-level operation restriction. This enforces interlock control of motorized equipment operations, ensuring operational safety.
