30-Channel Ethernet Relay Module with PoE

This 30-channel relay module allows you to manage multiple devices simultaneously through a single Ethernet port, using Modbus RTU and Modbus TCP protocols. Its support for Power over Ethernet (PoE) means you can power the device directly through the Ethernet cable, simplifying installation and reducing the need for extra wiring. Additionally, the module comes housed in a durable ABS rail-mount case for easy and secure installation in various industrial environments. It has a flash-on and flash-off function, allowing you to control the relays with precision by setting them to turn on and off automatically for a specified duration. With support for DC 7~36V wide-range power input and PoE, it offers flexibility in different projects. The module also supports relay control through the MQTT protocol, including an Alibaba Cloud MQTT application demo, making it perfect for IoT applications. The optocoupler isolation protects the relays from interference caused by high-voltage circuits, providing reliable performance in even the most demanding settings.
