Temperature measurement transducer MB-DS-30

Reference: MAX-MB-DS-30, EAN13: 5902431673912

Product description

Measurement transducer MB-DS-30 is designed for temperature measurement using temperature sensors (DS1820, DS18B20, DS18S20) connected in 1-Wire bus and for data exchange with external devices of Master type via RS-485 port in accordance with Modbus RTU standard.

Features
» support for Dallas sensors: DS1820, DS18B20, DS18S20;
» 1-Wire bus;
» up to 10 measuring points;
» readout of the current temperature;
» RS-485/Modbus RTU communication.

Functioning
The module continuously measures temperatures using external sensors. Readout of registered temperature values, setting of all measurement, communication and data exchange parameters are carried out through the RS-485 port using the Modbus RTU communication protocol. The switching on of the supply voltage is indicated by the green U LED.
The correct data exchange between the module and the other device is indicated by the yellow Tx LED.
The module works with the following 3-wire digital sensors:
DS1820, DS18B20, DS18S20.
Dedicated temperature probe made by F&F: RT-4 probe.
The probe is sold separately.
