General

Description

Four inputs for thermocouples, type J, K, S, N, R resolution 0.1 K, LEDs to indicate the status

The temperature input module can be operated with thermocouple sensors of type J, K, S, N, and R. It is equipped with 16-bit digital transducer resolution. The selected sensor type is used for the four inputs.

oFour inputs for thermocouples

oFor sensor types J, K, S, N, R

oIn addition, direct measurement of the raw values for other sensor types

oTerminal temperature compensation
