Ecosoft SG-Expander

The SG-Expander is an extension of the Ecosoft SG-Hub. The SG-Expander is connected to the SG-Hub with the supplied cable. A separate power supply for the SG-Expander is not needed.

This way, the SG-Hub will have 6 extra relays for switching purposes and 4 digital inputs to read-out and monitor. (The SG-Hub itself has two relays, among others used to operate heat pumps via SG-Ready connectors.)

No more than two SG-Expanders can be connected to the SG-Hub. The first SG-Expander is always connected to the SG-Hub, and the second SG-Expander is connected to the first SG-Expander.
