The PC301 8-Channel Network Relay Board, featuring Modbus TCP/RTU connectivity, is designed for remote control and automation of electrical equipment. With the online relay board, you can remotely switch on, off, or reset various devices. This unit is equipped with 8 relays for highly reliable control commands. Ideal for data centers, factories, poultry farms, greenhouses, and any facility requiring centralized remote equipment management, this network relay board enables efficient automation and smart environmental control.
In modern industrial automation systems, monitoring key parameters—such as temperature and humidity, carbon dioxide levels, and ammonia concentrations—is essential, but so is the ability to control them remotely. The PC301 Network Relay Board seamlessly integrates into automation systems, allowing remote control of heaters, fans, and other electrical devices for intelligent management of environmental conditions. Perfect for greenhouse automation, this relay board—paired with other monitoring modules—enables fully integrated smart automation solutions. Designed for DIN rail panel mounting, the network relay card supports Modbus protocol and can operate as an output expansion card for PLC systems, making it an ideal solution for advanced industrial automation projects.
The 8-Channel Network Relay Board is specifically designed for remote and intelligent control of electrical equipment over Ethernet and Modbus TCP/RTU protocols. This network-enabled relay card allows users to remotely switch devices on or off, making it ideal for industrial automation, remote facility management, and smart environmental control. Seamless PLC integration ensures the relay board can serve as a reliable relay output module in complex automation projects.
Thanks to its Modbus compatibility and network capabilities, the relay board can be easily integrated with various monitoring systems—such as temperature, humidity, pressure, and CO₂ sensors—to enable fully automated process control. For example, combining the relay board with a temperature and humidity measuring device allows precise climate control in smart poultry farms and enables advanced poultry house automation.
If your application requires additional features such as 4-20mA analog inputs or extra sensor connectivity, we recommend the Multi-Purpose Network Expansion Module. This advanced module offers Ethernet and Modbus protocol support, built-in GSM (SIM card) capability, and wireless data transmission—empowering you to receive alerts or control devices even when internet access is unavailable.
