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