D1-15P – 6 channel input modbus module for PT100
6-channel acquisition module for connection to a 2 or 3-wire PT100.
The read values are directly converted according to a linear scale with an accuracy of a few per thousand to the temperature value measured by the sensor. The Modbus driver will send the value to a unit of supervision.
Ramp conversion mode ensures a high reading accuracy that is maintained throughout the life time of the product.
The product does not need calibration operations during life time.
