Application note for PD 643

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: general module behaviour and interface.
Analogue Input channel: 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.
