MB-DS-30 measuring transmitter is designed for temperature measurement with temperature sensors
Product description:
MB-DS-30 measuring transmitter is designed for temperature measurement with DS18B20 temperature sensors connected in 1-WIRE bus and data exchange over RS-485 port according to Modbus RTU standard with external MASTER devices.
Functions:
- support of DALLAS DS18B20 sensors
- 1-WIRE bus
- up to 30 measurement points
- reading of current temperature
- rS-485 / ModbusRTU communication
Operation:
The module continuously measures temperatures with external sensors. Reading the values of recorded temperatures, setting of all measurement parameters, communication and data exchange are realized through 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 DS18B20 3-wire digital sensors.
