Application note for PD 641 / PD 643

Analogue input: 3 x (Pt100 / Pt1000) / Analogue input: 1 x (Pt100 / Pt1000)

Feature overview:

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:

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:

Alarming 
Notification
Signal out of range

Analogue Input Channel functions:

Analogue input 
Signal input filter
Offset adjustment
