Relay Output (Pro And Standard Version); Nmea 2000® Connection (Pro And Standard) - Sentinel Bm-50 Installationsanleitung

2.6 Relay output (Pro and Standard version)

The Standard version has one built-in low power relay while the Pro version has two. In
the Pro version, one contact of both relays is connected to the Relay Common wire.
In Standard version the load should be connected to the grey wire. In Pro version the
second load should be connected to the white wire.
To ensure proper functioning, the current must not exceed 1 A on each relay. The
maximum allowed switching voltage is 60 V. For switching loads that require more
power, an additional power relay is needed.
Example: switching low power LED light with Boat monitor.
2.7 NMEA 2000® connection (Pro and Standard)
CAN1 / NMEA2000 connector is a primary NMEA 2000 interface that connects to the boat
instrument NMEA2000 backbone. The Pro version has a secondary CAN2 multipurpose
CAN interface. Contact Sentinel support for more information.
Connect the CAN1 connector to the NMEA 2000® backbone (bus) via a drop cable and T-
connector. Important: Boat Monitor cannot be powered from the NMEA 2000® backbone.
