Overview

For many applications, WebRelay-Quad™ is the fastest, easiest, least expensive, and most reliable way to remotely control equipment over an IP network (including the Internet)!

WebRelay-Quad™ is used by many different companies for hundreds of applications including industrial control, security, remote control, remote reset, and many other applications that require remote relay control. It has four low-signal relays that can individually switch up to 3 Amp at 28V. Each relay can be turned on, off, or pulsed remotely using the built-in web pages or by running custom scripts from a computer or dedicated controller. It is extremely versatile and can be made to fit almost any remote relay control application.

The WebRelay-Quad is fully configured in minutes using a web browser. No additional software is needed.
