The wireless relay board is designed for controlling electrical equipment. This Card enables users to remotely switch on, switch off, or reset a variety of devices. The PC301W 4-port relay board allows users to easily control their equipment by simply connecting to Wi-Fi. One of the key applications of the wireless relay board (relay card) is remote lighting control—users can turn lights on or off either remotely or using the onboard push-button switches.
Another application of the online wireless relay board is its use in alarm systems—by connecting the device to a siren, it can notify users in case of any malfunction. In server rooms, the wireless relay card can be used alongside temperature and humidity monitoring to enable intelligent control and automation of server rooms and data centers, while also notifying data center managers of any incidents. Additionally, the relay board’s ports can be configured as four independent timer channels.
The wireless relay board (relay card) is designed to perform control commands (on/off/reset) either remotely or via the push-button switches on the device. By connecting the wireless relay board to WiFi, you can control electrical devices such as network equipment, lighting systems, sirens, police lights, fans, and more. Additionally, when the relay board is connected to monitoring devices like the chemical gas measurement device and the online temperature and humidity measurement device, you can manage these parameters as well. The wireless relay board is equipped with four relays, enabling you to control up to four electrical devices. Moreover, the device ports can also be used as timers.
One of the applications of the relay board is in poultry farming houses. With this device, you can control equipment inside the house—such as fans, heaters, inlets, and more. The relay board, together with devices like the pressure sensor, temperature and humidity measurement, carbon dioxide measurement, and other monitoring systems, facilitates the implementation of intelligent poultry farming automation. If you need more ports or LAN cable connectivity, the 8-port relay board is recommended. For more relays, temperature and humidity sensors, and input ports for automation, the UIO301G multifunctional network expansion module is suggested. This networked board is equipped with a SIM card module, supports the Modbus protocol, and can be connected to PLCs.
The Internet of Things (IoT) refers to a network of physical objects—billions of devices worldwide—that are now connected to the internet or other communication networks, enabling them to collect and share data. IoT is rapidly gaining applications across a variety of industries and businesses, including smart cities, smart homes, healthcare and medical systems, industrial automation, agriculture, and more. An IoT system collects and transmits data in real-time.
