The SeaGauge G4™ Sensor Interface Unit is a splash resistant unit that allows up to 3 engines and other vessel and performance data to be viewed simultaneously on a compatible display screens. Each Sensor Interface Unit can handle up to 24 different inputs (3 Pulse, 12 analog, 1 Serial) and 8 indicator inputs. All inputs can be min/max alarmed with visual and audible alerts. The Sensor Interface Unit provides digital instrumentation for a variety of performance parameters such as tachometer, EGT, boost, rpm, oil pressure, engine temperature, fuel level, voltmeter, main and auxiliary battery, and much more all in a compact sealed design. The integrated WiFi and CAN bus interfaces allows analog engine data to be transmitted via J1939/NMEA 2000 PGN’s and displayed on compatible MFD displays or other web browser devices such as iPads and Android tablets. Existing engines and equipment can be monitored in multiple locations using both wired (CAN bus) and wireless (802.11 a/b/g) interfaces. Housed in a solid ABS water-tight box, the Sensor Interface Unit can fit easily into most mounting locations. A built-in USB interface optionally transmits digital sensor data to PC/Laptop for real-time display. Embedded network interfaces allow gauge data to also be sent out over network data links (Wi-Fi or CAN Bus) and even directly to the Internet using HTTP/TCP/UDP protocols. The versatile design supports remote monitoring capabilities, giving you peace of mind whether you're at the helm or away from your boat. The system replaces existing gauges while using already installed senders or any new senders the user requires. Programmable calibration tables can be matched to almost any sensor. The SeaGauge G4 represents the next generation in marine instrumentation technology, delivering reliable performance for serious boaters who demand comprehensive system awareness.

  • MULTI-FUNCTION INTERFACE: SeaGauge G4 provides 24 different sensor interface functions with WIFI and CAN bus connectivity for comprehensive marine monitoring.
  • WIRELESS CAPABILITY: Integrated 802.11 a/b/g WIFI allows remote monitoring and control of your vessel's systems through compatible browser devices, MFDs, and applications.
  • EXTENSIVE COMPATIBILITY: Works seamlessly with various components including engine sensors, fuel flow sensors, analog gauges, fluid tanks, GPS, and marine instrument displays.
  • NETWORK INTEGRATION: Connects using CAN bus and compatible J1939/NMEA 2000/NMEA 0183 protocol devices for a complete vessel monitoring and control solution.
  • COMPREHENSIVE SUPPORT: Backed by Chetco Digital Limited with full US based technical support resources to ensure optimal performance of your marine monitoring system.
  • RUGGED DESIGN: Water and corrosion resistant sealed ABS enclosure and plugs designed for wet-deck installation measuring only 6" long x 5.125" tall x 2.5" thick – made in USA
