Note: 8 Channel IoT Ethernet Relay Controller (Support PoE and RS485) is discontinued now, we recommend 8 Channel Ethernet Relay Controller (Support PoE and USB) as a suitable replacement.
The RLY-8 is a network relay controller with open source communication protocol. It integrates 8 channel relays and each relay is able to stand 277VAC-10A or 125VAC-12A power. Since most of the household appliances are under 250VAC, this means you can use the RLY-8 relay almost everywhere!
The RLY-8 uses a STM32 microcontroller. It supports 2 types of power supply: Wall adapter or PoE (Power over Ethernet)(PoE) power supply. You can reduce its connection cable via PoE power supply. In addition, you can also control it via RS485 port or TCP/IP protocol. RS485 and JSON protocol has are opened on the website.
This Ethernet relays is really a neat choice for IoT(Internet of Things) projects - with 8 relays, you have plenty of scope to try on different things. Like a remote control light, a autoflowering greenhouse. With the open source protocol, you can add it in plenty of things and do with this besides, just use your imagination!
This new version Relay-8 module has support JSON now, please check network communication protocol.
