F&F MB-DS-2 temperature transmitter
- F&F MB-DS-2 temperature transmitter
F&F MB-DS-2 temperature transmitter
Product description
MB-DS-2 measuring transmitter is designed to measure temperature with an external DS1820 or DS18B20 temperature sensor and exchange data via RS-485 port according to MODBUS RTU protocol.
Features
- 2 independent measurement channels
- reading of current temperature
- reading of registered minimum and maximum temperature
- measurement result averaging time setting
- setting of the standard correction value
Operation
The module performs continuous temperature measurement by means of external sensors. Reading of recorded temperature values, setting of all measurement parameters, communication and data exchange are performed via RS-485 port
using MODBUS RTU communication protocol. Switching on the power supply voltage is signaled by the lighting of the green U LED. Correct data exchange between the module and the other device is signaled by the illumination of the yellow LED Tx.
The module works with DS1820 or DS18B20 3-wire digital sensors.
Dedicated temperature probe manufactured by F&F: RT-4 probe. Probe available separately.
MB Config
The program allows test reading of values and setting of communication and configuration parameters of the transmitter.
Communication of the transmitter with PC by means of USB converter WE-1800-BT.
