General

Description

Four analog inputs, 0...20 mA, resolution 12 bit, differential

The analog input module 24 Vdc is equipped with four inputs with 12-bit digital transducer resolution. The input signal is 0...20 mA.

  • Four analog inputs 0...20 mA

  • Open circuit detection

  • Adjustable digital input filters

  • Short cycle times

  • Ideal shield discharge on the channels

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.
