It integrates 8 channel relays and each relay could stand 277VAC-10A or 125VAC-12A power. Meanwhile most of the household appliances are under 250VAC, it means you could use it almost everywhere. The RLY-8 is using STM32 microcontroller. It supports 2 types of power supply: Wall adapter or PoE (Power over Ethernet) power supply. You could reduce its connection cable via PoE power supply. In addition, you also could control it via RS485 port or TCP/IP protocol. And RS485 and JSON protocol has been opened on the website. This Ethernet relays are really great for IoT projects - with 8 relays, you have plenty of scope to try different things. Like a remote control light, a autoflowering greenhouse. With the open source protocol, you could add it in plenty of things you can do with this besides, just use your imagination! Specification            Operating Voltage: DC:7-23V Relay number: 8 Data Communication: Ethernet/RS485 Network Configuration: Supports DHCP and Static IP Power Consumption: Max 3.5W Maximum Control: 277VAC-10A/125VAC-12A Control Mode: Ethernet/RS485 Factory Settings: IP: 192.168.1.10 (port: 2000) Working Temperature: -30~85 Weight: 530g Size: 145mm * 90mm * 40mm (5.7in * 3.5in * 1.6in) Tutorial Requirements  Hardware POE relay x1 PC X1 USB to RS485 transfer line or ethernet cable POE Ethernet switch or ordinary Ethernet switch  Software PC Software (Windows) Click to Download Connection Diagram RLY-8-PoE-RS485 supports 2 types of control mode: Ethernet and RS485 In this section, we will introduce some typical connection:  Ethernet NOTE: If you directly connect to the computer, you will need to set a static IP. Going by RLY factory settings, you can set your computer IP to 192.168.1.x(x is 0~254 except 10), Subnetmask 255.255.255.0, gateway 192.168.1.1  RS485 BUS PC Control of POE Relay Open the Software Select the network, and then select the network Control button, enter the network control interface NOTE: It may take some time when the RLY-8 has just been powered on, please be patient waiting for the network list Network Control of POE Relay NOTE: It is recommended to click the "Get Status" button to get the current state when you want to control the relay. Control the POE relay with RS485 BUS   Reset and Restore Factory Settings To reset the factory default settings, hold the reset button until the lights begin to flash.  Control For any questions/advice/cool ideas to share, please visit DFRobot Forum.   Powered By DFRobot © 2008-2017
