Model: ASC-4 0-190, 10-180, 240-30 or self-defined (4 channels)
Operating temperature: -30 - +75°C
IP rating: IP67
LENGTH = 1
- NMEA2000 converter
- For four analog sensors
- IP rating IP67

The WEMA GPS speedometer is a speedometer that accurately displays the current speed (speed over the bottom) and direction (direction over the bottom). The speedometer displays speed analogically and direction digitally, both values ??are based on GPS signals. The GPS Speedo has a 32-channel GPS receiver. The meter is suitable for all types of boats and is easy to install.
- Installation Ø 85 mm
- Installation depth 55 mm
- Standard red and yellow lighting
- Operating voltage 12 V
- Speed ??range 0-60 knots
- White base / white frame

Used when multiple sensors and devices are installed on the same NMEA2000 network. In this case, each sensor and device must be assigned its own correct instance number.
The installation tool is also used to reprogram the sensor, for example from fuel to water. The Wema N3/N5 is supplied as a fuel sensor as standard, while the Wema N3H/N5H is supplied as a septic tank sensor as standard.
- NMEA2000
- For programming sensors
