The Samyung TB-70S Terminal Box is an optional accessory for the Samyung SI-70A Class A AIS Transceiver system. Its primary function is to serve as a passive junction point or wiring interface for the SI-70A unit, allowing for the organized and simplified connection of various external equipment and sensors. This box typically provides labeled screw terminals where installers can securely connect the numerous NMEA 0183/422 data lines, power supply wires, and alarm outputs from other onboard navigation devices (like GPS, Gyro Compass, ECDIS, and Radar) before they are consolidated into the main AIS unit, thereby improving the overall system wiring and installation flexibility.
