The DIN-130 thermocouple input Modbus modules convert analog input signals to digital data and transmit via RS-485 using the Modbus RTU protocol for communication. The modules provide a wide variety of ranges and perform all signal conditioning, scaling, thermocouple linearization and conversion to either linearized ASCII data values or Modbus percent of full scale binary values.
