Application note for PD 642 / PD 643
Analogue input: 4 x 0-100mV / Thermocouple / Analogue input: 3 x 0-100mV / Thermocouple
Feature overview:
The PD 642 contains 4 and the PD 643 contains 3 analogue channels, each of which can be configured for use with an input signal of: 0 to 100mV or one of a selection of thermocouples from the range:
Type E – (-94.8 – +1000 C)
Type K – (-153.7 – +1372 C)
Type N – (-270 – +1300 C)
Type R – (-50 – +1768 C)
Type S – (-50 – +1768 C)
Type T – (-166.5 – +1000 C)
All PROCES-DATA modules are based on the Channel concept. A channel is a functional object, consisting of both functions and all function-related data.
A PD 642 / 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
– Alarming
– Notification
Analogue Input Channel functions:
– 0-100mV input signal scaling to SI unit
– Thermocouple input signal scaling
– Thermocouple offset adjustment
– Signal input filter
– Simulation
