Analog module with 6 PT100 2/3 wire input channels
6-channel temperature acquisition module for direct connection to 2 or 3 wire PT100.
The values are converted directly on a linear scale in a number with high accuracy ( few units per thousand ) corrisponding to the value of the temperature measured by the sensor. The Modbus driver will send the number to application program ( SCADA ) according to MODBUS protocol comunication parameters The ramp conversion provides high readability that is maintained throughout the lifetime of the product, avoiding absolutely recalibration procedures.
