Teracom Digital temperature sensor TST300v2


Model TST300v2

Short Description

TST300v2 is a precision temperature sensor with MODBUS RTU interface. The device doesnt need an external power supply, it is powered through the interface. It is an excellent solution for precision temperature monitoring and control.

The temperature sensor integrates a band-gap temperature sensor element plus signals 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, drug and 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 0.13C in +20 to +60C range. It works with 12 bits precision from the onboard digital-to-analog converter. The current consumption is lower than 5mA, with the supply voltage from 4 to 5.5VDC.

TST300v2 communicates with controllers over an RS-485 interface. Each sensor has a unique serial code, which allows multi-sensors support over the same RS-485 bus. Shipment includes a one meter cable.

The digital temperature sensor utilizes two RJ45 connectors for an easy daisy chain wiring. Standard UTP/FTP patch LAN cable can be used for interconnection between the sensors and the controller.

The digital temperature sensor can be used with

* Ethernet IO module TCW241
* Ethernet data logger TCW220
* Remote IO module TCW122B-CM
* GSM-GPRS remote monitoring controller TCG120
* IP watchdog monitoring module TCW122B-WD
* Remote environmental monitoring module TCW112-CM
* IP watchdog relay board TCW112-WD


* 0.13C accuracy from +20C to +60C;
* 14 bits resolutions;
