Product description: Tinycontrol tMDS-16 - temperature meter - Modbus RTU - up to 16 DS18B20 sensors
The tMDS-16 is a professional module designed for temperature measurement using DS18B20 digital sensors . It features two independent 1-Wire buses , each supporting up to 8 sensors, allowing simultaneous temperature readings from up to 16 measurement points. All data is shared via the Modbus RTU RS485 protocol , allowing for easy integration with automation systems and PLCs . The module also offers the ability to individually calibrate each sensor using offsets, ensuring accurate and consistent measurements. Thanks to pre-built configuration files, it works with LK4, LK3.5+, and LK3.9 controllers, enabling quick implementation into existing installations.
Tinycontrol tMDS-16 - temperature meter - Modbus RTU - up to 16 DS18B20 sensors.
The tMDS-16 is designed to operate as an expansion module for LK4, LK3.9 or LK3.5+ devices.
