The quad WebRelay is a solution for applications such as industrial control, security, remote control, remote reset, and many other applications that require remote relay control over an IP network.
Typical applications include:
- Pumps
- Valves
- Motors
- Lights
- Gates
Each relay can be turned off, on and pulsed remotely using the build in web page/control page or custom script from a PC or dedicated controller.
