Description

APPLICATION
The PD 643 is an analogue input module with one Pt-100/Pt-1000/thermocouple/ 0-100 mV input channel and two thermocouple/0-100 mV input channels. All inputs can be configured for thermocouple/0-100 mV sensor input. A Pt-100 / Pt-1000 temperature sensor can be connected to channel 1 and may be used as a reference temperature for the thermocouple sensors connected to channel 2 and 3. The thermocouple inputs are floating. The PD 643 provides linearization for the following types of thermocouple transducers: Type R, S, B, J, T, E, K and N.

The PD 643 is used with a BM 013 Base module.

A PD 991 Pt-100 sensor can be very useful if channel 1 is to be used as a temperature reference for thermocouple sensors connected to the channels 2 and 3.
