8-Channel Ethernet Relay Module with PoE for Remote Control ✔️ 8-ch relay board, PoE power, 7-36V DC input, ABS rail-mount

The Modbus POE ETH Relay is an industrial 8-channel Ethernet-controlled relay module designed for remote switching and monitoring in automation, building management, and process control contexts. It supports Modbus RTU/Modbus TCP, DHCP, DNS, MQTT, HTTP, and can be powered by PoE or a wide 7-36V DC input.

✅ Eight independently controllable relays rated up to 10A 250VAC / 30VDC
✅ Onboard optocoupler isolation for digital inputs
✅ Modbus RTU/TCP over Ethernet with MQTT and HTTP interfaces
✅ PoE power option plus DC input and DHCP/DNS support
✅ ABS rail-mount enclosure with status LEDs

💡 What is an Ethernet relay module used for in industrial automation and remote control? It’s a handy device that lets you switch loads over a network from a central controller.

- remote control of industrial loads via Modbus RTU/TCP and MQTT
- easy integration with PLCs and SCADA for automation workflows
- flexible power options: PoE or 7-36V DC for field deployments
