WaveShare Modbus

The PoE ETH 8-CH Relay Module is an industrial-grade 8-channel relay that is controlled via Ethernet and uses the Modbus RTU protocol. It offers numerous protection circuits, easy handling, and reliable performance for industrial control applications. With a contact rating of ≤10A 250VAC/30VDC, it is ideal for controlling household appliances and devices under 30VDC. The rail-mounted ABS housing allows for easy and secure installation.

Recommended accessories: 12V DC 4000mA power supply AC/DC adapter with 5.5mm/2.1mm connector, Ethernet patch cable RJ45 Cat.6 network cable.

Features: The Flash-ON, Flash-OFF function allows the relay to automatically turn off after a set time. It supports DC 7~36V input voltage and PoE power supply. It supports relay control via MQTT protocol and comes with an Alibaba Cloud MQTT application demo. The optocoupler isolation prevents the relay from being disturbed by high-voltage circuits. The circuit is reverse polarity protected and safeguards against accidental wrong connections. The relay has 4 LEDs as status indicators.
