Waveshare Industrial 8-Channel Ethernet Relay Module Modbus POE ETH Relay for Industrial Equipment Control

Description:
- This product is an industrial 8-ch relay module controlled via Ethernet port, adopts Modbus RTU/Modbus TCP protocols, supports PoE power supply, also comes with an ABS rail-mount case.
- The Modbus POE ETH Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.

Features:
- Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically
- Supports DC 7~36V wide range power input and PoE power supply
- Supports relay control through MQTT protocol, comes with Alibaba Cloud MQTT application demo
- Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High-quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail-mounted ABS case, easy to install, safe to use
- 4 LEDs and Network indicators for indicating the MCU status and signal transceiving status

Functions:
- Basic function: supports sending for Modbus RTU/TCP protocol commands via Ethernet port to control relay and various devices.
- Support multiple communication modes, adopts for Modbus protocol; support for TCP server, for TCP client, for UDP mode, for UDP multicast, for HTTP, for MQTT, for Modbus RTU protocol and for Modbus TCP protocol.
- Multi configuration methods: supports software and web browser configuration, obtaining dynamic IP via DHCP, connecting to domain name server via DNS protocol.
- Multiple power supply options and wide range power input:
  DC power port: directly uses a power plug for power supply
  Screw terminal: DC7 ~ 36V wide range power input
