INF2212
Our K-PT module is designed to connect PT100/1000 sensors to a K-Box or K-AN8 voltage measurement device that normally cannot support these sensors. The powered K-PT module enables PT100/1000 sensors to be connected via the D-Sub 9 terminals and will output the signal voltages to an Analogue measurement device.
Calibration and sampling rates can be configured using the freely distributed K-Cal software.
Connects up to 4 RTD sensors to the K-Series K-Box/K-AN8 via the Analogue inputs
Simple signal configuration using a DBC file
