Features:

• With flash-on and flash-off functions, you can add parameters to the relay's operating command to automatically turn off after a certain time.
• Supports a wide voltage DC power supply of 7-36V, supports PoE Ethernet power supply.
• Supports relay control via MQTT protocol and provides Alibaba Cloud MQTT application routines.
• Built-in optoisolator isolation to prevent interference from high voltage relay circuits.
• Adopts a special relay driver chip, with built-in flyback diode protection, stronger and more stable driving capability.
• Active switch input, built-in de-jitter algorithm, relay supports switch input connection mode or reverse control mode.
• Integrated anti-reverse connection circuit to avoid reverse connection of positive and negative poles and burning of the circuit (only version B with 8 directions).
• Uses high-quality relays, allowing load access: less than or equal to 10A 250V AC or less than or equal to 10A 30V DC.
• Protective ABS shell type rail, easy to install and use, safer with the shell.
• Four external LED indicators and a network port indicator light facilitate monitoring of MCU status and signal transmission and reception status.
