The EHR speed control relay is designed for controlling the actuator connected to the throttle of internal combustion engines. With actuator control, the engine engages safely at low RPM and automatically increases RPM after the time set via the relay has elapsed. The EHR speed control relay is user-friendly due to its ease of use and software developed to meet specific needs. The duration for which the internal combustion engine operates at low RPM can be adjusted via the menu. The countdown for the low-RPM operation time can be monitored on the LED display, and the current status can be tracked through the notification LEDs.
