The power line and the foot switch line use screw quickconnect terminals, enabling fast and reliable connections with reduced risk of loose contacts. The input time and current are set with a precision unit potentiometer, delivering reliable and convenient input adjustments. Strong and weak signals are isolated through an optocoupler, providing electrical isolation between control circuitry and power circuits to improve safety and reduce interference. The main control core is an STM8 industrial singlechip microcomputer, providing stable and robust processing for industrial applications. 23 use scenarios In automated equipment panels that require precise timing and current control for actuators, sensors, or relays, enabling reliable operation and repeatable results. In power or motor drive systems where electrical isolation between control signals and power circuits is essential for safety and noise immunity. In development, testing, or service benches where straightforward wiring, dependable control, and easy parameter adjustment simplify experimentation and validation of timing and current benchmarks.
