WebRelay-10™ is a robust, industrial relay board with Ethernet communications. It provides remote relay control through its ten large 30A relays.

The relays can be individually controlled using a standard web browser or by sending commands from a custom control application. It is self-contained with a built-in web server, and requires no external software, additional network modules, or computers.

WebRelay-10 is designed for industrial applications and can be DIN-Rail mounted inside a control cabinet. Tab connectors (1/4 inch) are used for power and relay contact connection.
