Modbus RTU Temperature Sensor – TST300
The TST300 is a Modbus RTU temperature sensor for high-precision industrial applications in the -20 to +60°C range.
Description
TST300 is a Modbus RTU temperature sensor designed for reliable industrial temperature monitoring and control. It delivers high-precision digital measurement and communicates directly with PLCs, data loggers and building automation systems.
The device integrates a calibrated temperature sensing element with digital signal processing, providing stable and repeatable results. Each unit is factory-calibrated and ready for immediate installation.
It is suitable for server rooms, telecommunications facilities, industrial cabinets and environmental monitoring applications where accurate temperature control is required.
The sensor operates in the -20 to +60°C range with measurement accuracy up to ±0.13°C.
It communicates over an RS-485 interface using the Modbus RTU protocol and supports multi-drop configuration on a shared bus.
Low power consumption allows operation without external supply in many configurations, while the device operates within a 4 to 5.5 VDC range.
Two RJ45 connectors enable simple daisy-chain wiring using standard UTP/FTP patch cables for fast integration with controllers.
