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.

Four inputs for thermocouples
For sensor types J, K, S, N, R
In addition, direct measurement of the raw values for other sensor types
Terminal temperature compensation

Parameterizing the Module Via PLC Configuration

In order to parameterize a module per PLC Configuration in the device editor, proceed as follows:

Step	Action
1	Append module in the Devices tree beneath a Sercos III bus interface (TM5NS31).
2	Afterwards double-click the module in the Devices tree. Result: The device editor is opened and the tabs TM7 Module I/O display, User-defined parameters, and Information are displayed.
