The Devantech ETH8020-B Ethernet Relay (20 x 16A) is an advanced relay module designed for remote control via Ethernet using straightforward TCP/IP commands. This upgraded version of the ETH8020 includes enhanced features such as MQTT and email capabilities, both of which support optional TLS encryption for secure communication. The module is equipped with 20 relays, each capable of handling up to 16 amps at 24VDC or 250VAC, and includes eight analogue inputs ranging from 0 to 5 volts.
The device operates on a 12V DC power supply, which is sold separately.

The ETH8020-B supports a 100mb full duplex Ethernet connection and offers screw terminals for N/O, N/C, and common contacts. Additionally, the hostname is now configurable, and the device maintains drop-in compatibility with its predecessor, the ETH8020.
Remote control of the module is facilitated by free Android and iPhone applications, enhancing its usability in various applications. Optional accessories such as power supplies, cases, and cables are available separately.
Note: Ensure proper handling of electrical connections to avoid hazards.
