Yacht Devices YDTC-13R Digital Thermometer with SeaTalk NG Connector, -55 to +125°C
The Yacht Devices YDTC-13R is a digital marine thermometer designed for precise temperature measurement in SeaTalk NG and NMEA 2000 networks. It measures gases and liquids over a range from -55 to +125°C (-67 to +257°F) and transmits temperature data to compatible chart plotters, digital navigation instruments and other onboard equipment.
The YDTC-13R version is equipped with a Raymarine SeaTalk NG Female connector. The temperature sensor is located outside the device case in a sealed stainless-steel sleeve and is connected by a flexible 950 mm cable that can be extended up to 100 meters when required.

NMEA 2000 Data Output
The YDTC-13R can transmit temperature information through several NMEA 2000 PGNs depending on the selected temperature type and the capabilities of the connected instruments.
- PGN 130310
- PGN 130311
- PGN 130312
- PGN 130316
The transmission interval for periodic messages can be configured from 50 milliseconds to 1 hour. Setting the interval to 0 disables transmission of the selected PGN.
Historical Temperature Data
The thermometer stores temperature measurements from the previous 48 hours in internal RAM. Historical data can be retrieved using compatible software such as CAN Log Viewer or compatible NMEA 2000 hardware.
Digital Switching Support
With firmware version 1.50 or later, the YDTC-13R can control compatible NMEA 2000 digital switching channels supporting PGN 127502 Switch Bank Control.
- Up to 3 configurable ON rules
- Up to 3 configurable OFF rules
- Switching based on actual temperature
- Configurable condition delay
- Can be used for automatic pump, ventilation or alarm control through compatible switching equipment
Sensor Cable Extension
The standard 950 mm sensor cable can be extended by the user up to 100 meters. A three-conductor extension cable with a conductor cross-section of at least 0.2 mm² and a conductor diameter of at least 0.5 mm is recommended.
- Maximum sensor cable extension: 100 m
- Minimum conductor cross-section: 0.2 mm²
- Minimum conductor diameter: 0.5 mm
- Suitable cable categories include UTP 3, UTP 5 and UTP 5e with AWG-24 or AWG-22 conductors
The cable should be routed away from strong electromagnetic interference sources such as motors, compressors, generators, electric pumps and transmitting antennas.
Installation
The YDTC-13R connects directly to the SeaTalk NG / NMEA 2000 bus without a drop cable. Bus power should be switched off before installation.
The device itself should be installed in a dry location. The external stainless-steel sensor sleeve is waterproof, but it is not intended for permanent installation in hostile environments such as seawater.
