XI. NMEA 2000 Digital Switching Support
To make your system more flexible and scalable, we have added an expert option that makes the Battery
Monitor more than just a measurement data source. The Device is capable of managing of NMEA 2000
digital switching equipment by user-defined rules (see IX.3 and examples in Section IV).
Depending on measurement results, the Device can automatically turn on or off any of 28 Digital Switching
channels which can activate other connected devices, e.g., raise a sound alert, turn on a battery charging
genset, switch off a power consumer, etc.
The Battery Monitor supports NMEA 2000 digital switching equipment that is managed with NMEA
2000 Standard PGNs 127501 and 127502. The Device can send commands to turn on/off electrical loads
connected to external NMEA 2000 two-state devices (e. g. relay banks).
Products described in this chapter may become a valuable addition to your digital switching system.
1. Yacht Devices NMEA 2000 Circuit Control YDCC-04
The Circuit Control incorporates one bank of four latching (bi -stable) relays capable of switching direct
current (DC) and alternating current (AC) loads. The Battery Monitor can be used to monitor amperage
in DC loads connected to the YDCC-04, and automatically turn them ON and OFF depending on user
rules. For example, you can set up the Battery Monitor to switch OFF a load when battery current exceeds
a pre-defined value, or switch to another battery/bank if the measured voltage drops below the set
threshold.
2. Yacht Devices Alarm Button YDAB-01
The Alarm Button acts as a digital switching «music box»; it incorporates a powerful sound amplifier with
a loudspeaker output. Battery Monitor can turn ON any of Alarm Button's 28 alarm sounds (preset or user-
uploaded). For example, you can automatically activate an alarm when the battery's voltage is running low.
