WebRelay™ provides reliable remote relay control and discrete signal monitoring over any IP network. WebRelay can be used in countless applications, including pump and motor control, security lock systems, remote reboot, and lighting control. WebRelay’s powerful and flexible design make imagination its only limit. In addition to its built-in relay, WebRelay 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 or sensor to control a device at a distant location.
