Temperature sensor with RS485, -20 to +60°C, Modbus RTU interface, 14 bit resolution, cascade connection

TST300 is a precision temperature sensor with MODBUS RTU interface. The device does not require an external power supply. It is an excellent solution for precise temperature monitoring and control.

The temperature sensor integrates a band-gap temperature sensing element plus signal processing and provides a fully calibrated digital output. The temperature sensor is factory calibrated.

It focuses on applications that require precise temperature monitoring - server rooms, offices, food stores, etc. It is also suitable for smart office applications, as well as for data loggers and thermostats.

The temperature sensor provides high measurement accuracy as low as ± 0.13°C in the +20 to + 60°C range. It operates with 12 bits precision from the on-board digital-to-analog converter. The current consumption is lower than 5mA, while the supply voltage is from 4 to 5.5VDC.

The TST300 communicates with controllers over an RS-485 interface. Each sensor has a unique serial number, which allows multiple sensors to use the same RS-485 bus.

The digital temperature sensor uses two RJ45 connectors for an easy way to daisy chain to the next module. Standard UTP/FTP LAN cable can be used for interconnection between the sensors and the controller.
