The HUB has 2 digital I/Os which can be used to control the relays for switching heavy loads. It further has an analogue input for voltage measurements up to 60V and a differential input for current measurements when connected to a shunt. It also has an integrated temperature, humidity and pressure sensor.
Sometimes older boats need to be retrofitted with Sentinel Telematics. To avoid cabling, the installer can use up to 4 HUBs for connecting measurement sources or switching relays.
Pairing of Hubs is done effortlessly via the Sentinel app.
