WebRelay is an electrical relay (or electrical switch) with a built-in web server. The relay can be turned on, off or pulsed using a web browser. It has a long history of reliable operation in many applications including remote reboot, industrial control, security and remote control and monitoring.

WebRelay can provide remote relay control in countless applications including pump and motor control, security lock systems, remote reboot and lighting control.

It also has an optically isolated input that can be used to monitor the state of devices, control the relay, or control a remote relay somewhere else on the network. This feature is useful to extend the output of a PLC to another building or to allow a switch to control a device in another state.

WebRelay can even be used without a computer (once setup is complete) by connecting two units together. This is done by connecting a switch or applying a control voltage to one unit, and connecting a second unit at a remote location to the device to be controlled.
