Waveshare 30-Channel Ethernet Relay Module with Modbus RTU/TCP, PoE Communication & Isolation Protection
Waveshare 30-Channel Ethernet Relay Module with Modbus RTU/TCP, PoE Communication & Isolation Protection
The Waveshare 30-Channel Ethernet Relay Module is an industrial-grade network relay controller designed to provide reliable remote switching and device control through Ethernet communication. It features 30 independent relay channels and supports both Modbus RTU and Modbus TCP protocols, making it suitable for integration with industrial automation and control systems.
The module supports IEEE 802.3af PoE for convenient power and network connectivity, while an external DC 7–36V power input is also available. Each relay has a contact rating of ≤10A 250VAC/30VDC, allowing the module to control compatible AC and DC loads. For safer and more stable operation, it incorporates optocoupler isolation, a dedicated relay driver with built-in flyback diode protection, and reverse-proof circuitry.
It also supports TCP Server, TCP Client, UDP, UDP Multicast, HTTP, and MQTT, along with software and web-browser configuration, DHCP and DNS. Housed in an ABS rail-mount case with dimensions of 300 × 110 × 60mm and a weight of 0.886kg, this 30-channel Modbus Ethernet relay is a practical choice for industrial control, IoT automation, remote switching, and applications requiring multiple network-controlled relay outputs.
Features:
- Features flash-on and flash-off functions; by giving an argument to the command, it is possible to turn on the relay for a while and then close it automatically.
- Supports DC 7–36V power input and PoE power supply.
- Supports relay control over the MQTT protocol, and includes an example of the Alibaba Cloud MQTT application.
- Onboard Optocoupler isolation protects the relay from interference from high-voltage circuits.
- Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more steady driving.
- Reverse-proof circuit prevents the circuit from being accidently destroyed by an incorrect connection.
- High-quality relay with contact rating of ≤10A at 250VAC/30VDC.
Rail-mounted ABS plastic enclosure is easy to install and safe to use. - Four LEDs and network indicators indicate the MCU state and signal transceiving status.
Package Includes:
- 1 x Modbus POE ETH Relay 30CH
