HW-521 Adjustable Timing Cycle Relay module
HW-521 adjustable timing cycle relay module for Arduino, Raspberry Pi, and microcontroller projects with ON/OFF cycle control.
Description
The HW-521 Adjustable Timing Cycle Relay Module is a versatile relay module designed for precise on/off cycle control of AC or DC devices. It features an adjustable timing cycle, allowing users to set both the ON and OFF durations according to project requirements.
Operating at 12V control voltage, this module can safely switch loads such as lights, motors, fans, and other appliances. It is ideal for industrial automation, home automation, irrigation systems, robotics, and DIY electronics projects. Equipped with indicator LEDs, opto-isolated input for protection, and screw terminals for secure wiring, the HW-521 ensures reliable and safe operation. Compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers, it provides flexible timing control for a wide range of applications.
