Definition

Relay Self-Locking is a control method that enables precise equipment control via industrial remote controls, determining the operator's ability to control equipment speed, direction and accuracy.

In-Depth Analysis

Different working conditions have different requirements for Relay Self-Locking: simple start/stop scenarios use single-speed control (e.g., LDER LD-6SK), while scenarios requiring precise positioning use dual-speed or VFD stepless speed regulation (e.g., LD-10DK dual-speed, LD-12DK multi-speed). The XINGJIA series also offers single-speed, dual-speed, multi-speed and proportional joystick control options. Relay Self-Locking also involves safety control logic such as emergency stop, interlock and zero-position protection to ensure operational safety.
