Product Description

The PD 642 is an analogue input module with four voltage input (0-100 mV) channels.
The four input channels can be configured individually for either 0-100 mV or thermocouple temperature sensor input.
The PD 642 provides linearization for the following types of thermocouple transducers: Type R, S, B, J, T, E, K and N.

It is used with a BM 014 Base module.
