30-channel relay PoE Ethernet module RTU/Modbus TCP protocol

With this 30-channel Ethernet relay module, you can take your device control to the next level. This module is specifically designed for demanding industrial applications and supports both the Modbus RTU and Modbus TCP protocols. The power supply is provided either via PoE or through a wide DC input, allowing for flexible application possibilities. Thanks to optical isolation, the module is particularly safe and protects against interference from high-voltage lines. The stable ABS housing design and the possibility of DIN rail mounting make the module robust and easy to install. With MQTT support, you can also use the device in the cloud, enabling easy integration into modern IoT environments. Four LEDs provide clear status indicators, so you have an overview at all times. For configuration, you can choose between software and web browser methods. An ideal module for remote control of household appliances or industrial systems.
