Application note for PD 641 / PD 643
Analogue input: 3 x (Pt100 / Pt1000) / Analogue input: 1 x (Pt100 / Pt1000)
The PD 641 contains 3 analogue channels, which can be configured to measure Pt100 or Pt1000 sensor elements.
The PD 643 contains 3 analogue channels, of which only Channel 1 can be configured to measure Pt100 or Pt1000 sensor elements.
The analogue input register shows the temperature in °C.
A PD 641 / 643 module consists of 2 channel types:
– Service channel:
– Analogue Input channel:
General module behaviour and interface
Functions and data for analogue input.
Analogue Input channel description:
Input channels provided by PROCES-DATA contain much more than just the basic input function. The input channel functions and associated parameters are formed into a channel description. The module’s integrated controller handles all channel functions.
Functions need only to be configured for operation. No additional programming is required.
Analogue Input Channel monitors:
– Signal out of range
Analogue Input Channel functions:
– Analogue input
– Signal input filter
– Offset adjustment
Pt100 / Pt1000 Offset adjustment
