Switch remotely...
With the Web-IO 4.0 230V Relay 1xNO, 1xCO 230V switching signals can be controlled via TCP/IP Ethernet. There are numerous Web and network services available for switching up to 16A with the two integrated relays - even directly from the browser or from a smart phone. Using protocols such as MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.
