General

Description

Four inputs resistance measuring, 2- and 4- wire measuring, PT100, PT1000, KTY10,KTY84, resolution 0.1 K, LEDs to indicate the status.

The temperature input module can be operated with resistance temperature detectors of type KTY10, KTY84, PT100, and PT1000. The sensors can be connected with 2- or 4-conductor technology. The sensor type can be adjusted selectively for each input.

It is equipped with 16-bit digital transducer resolution.

Four inputs for resistance temperature measurement
For the sensor types PT100, PT1000 and others
In addition, direct resistance measurement
Sensor type adjustable per channel

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.

Tab TM7 Module I/O Display

The input and output channels of the module are mapped to project variables that are used by the application.

Channel	Meaning	Default value	Data type
RTD input 1	Temperature of input 1	–	INT
RTD input 2	Temperature of input 2	–	INT
RTD input 3	Temperature of input 3	–	INT
RTD input 4	Temperature of input 4	–	INT
Status of analog input 1	Status of the analog input 1	–	BOOL
Status of analog input 02	Status of analog input 02	–	BOOL
Status of analog input 3	Status of the analog input 3	–	BOOL
Status of analog input 4	Status of the analog input 4	–	BOOL

Tab User-Defined Parameters

The values are set via a selection list.

The check box Symbolic values is used for switching between the numeric and the symbolic value.
