Description

The 8-channel Ethernet Relay Module is a versatile and robust control device designed for industrial and automation projects, offering advanced features and compatibility with various communication protocols. This module provides eight relay channels, each capable of switching high-power electrical loads. These channels can be independently controlled, making them suitable for a wide range of applications.

It supports both Modbus RTU and Modbus TCP communication protocols, enabling seamless integration with industrial automation systems, PLCs, and SCADA systems. It also supports the MQTT (Message Queuing Telemetry Transport) protocol, allowing for efficient and real-time communication with IoT devices and cloud platforms.

The module features a PoE port, which simplifies installation and reduces the need for additional power supplies and wiring. PoE provides both power and data connectivity over a single Ethernet cable, enhancing flexibility in deployment. For safety concerns, there are onboard optocouplers that provide electrical isolation between the relay control circuitry and the external devices connected to the relays. This isolation enhances safety by preventing voltage spikes or surges from affecting the control system.

This module is a versatile and reliable control solution for various industrial and automation applications. Its support for multiple communication protocols, PoE connectivity, optocoupler isolation, and MQTT compatibility makes it a powerful tool for remote monitoring and control. Additionally, the Alibaba Cloud MQTT application demo simplifies the integration of the module into cloud-based IoT solutions, enhancing its usability and functionality.
