WaveShare 8-channel relay (B) PoE Ethernet module RTU/Modbus TCP protocol

The 8-channel relay (B) from WaveShare is a versatile and reliable Ethernet relay module specifically designed for industrial automation applications. It supports both Modbus RTU and Modbus TCP protocols, enabling efficient communication over Ethernet. The integrated Power over Ethernet (PoE) feature reduces installation effort as no additional power supply is required. With eight relay channels and eight digital inputs, the module offers comprehensive control options and flexibility for various circuits. The bidirectional optocoupler isolation protects the digital inputs from interference, enhancing reliability in demanding environments. Its robust construction and the option for DIN rail mounting make integration into industrial systems simple and secure. Multiple status LEDs allow for quick verification of operational status and data communication, while various communication modes such as TCP Server, TCP Client, UDP, and MQTT provide a wide range of application possibilities.
