Measurement temperature transducer MB-DS-2

Measurement temperature transducer MB-DS-2

MB-DS-2

Two-channel with MODBUS RTU output.
MB-DS-2 measurement transducer is designed to measure the temperature via DS1820 external temperature sensor and to transmit data via RS-485 port using MODBUS RTU protocol.

Features
* two independent measurement channels
* readout of the current temperature
* readout of the recorded minimum and maximum temperature
* setting the averaging measurement time
* setting the value of standard adjustment
  

Operation
The module continuously measures the temperature using the external sensors. Readout of recorded temperatures, setting of all measurement parameters, communication and data transmission are all carried out through RS-485 port using the MODBUS RTU communication protocol. Power up is indicated by a green LED U. Valid data exchange between the unit and the second device is indicated by a yellow LED Tx. The unit cooperates with the three-wire DS1820 digital sensors. Dedicated temperature probe manufactured by F&F: RT-4 probe.
The probe is sold separately.
