Siemens Simatic 6ES7-331-7KF02-0AB0 Analog input module

6ES7-331-7KF02-0AB0 Properties

8 inputs in 4 channel groups

Programmable measurement type at each channel group

– Voltage

– Current

– Resistance

– Temperature

Programmable resolution at each channel group (9/12/14 bits + sign)

Any measuring range selection per channel group

Programmable diagnostics and diagnostic interrupt

Programmable limit value monitoring for 2 channels

Programmable hardware interrupt when limit is exceeded

Electrically isolated to CPU and load voltage (not for 2-wire transducers)

6ES7-331-7KF02-0AB0 Resolution

The measured value resolution is directly proportional to the selected integration time, that is, the measured value resolution increases in proportion to length of the integration time at the analog input channel.

6ES7-331-7KF02-0AB0 Hardware interrupts

Hardware interrupts for channel groups 0 and 1 can be programmed in STEP 7.

However, set a hardware interrupt only for the first channel of a channel group, that is, either at channel 0, or at channel 2

6ES7-331-7KF02-0AB0 Terminal assignment

The diagrams below show various wiring options The input impedance depends on the setting of the measuring range module, see table Measurement types and ranges

6ES7-331-7KF02-0AB0 Introduction

Module SM 331; AI 8 x 12 Bit has measuring range modules

The measurement type and range is configured at the "measuring range" parameter in STEP 7.

The default setting of the module is "voltage" measurement with "± 10V" range. You can use

these default settings without having to program the SM 331; AI 8 x 12 Bit in STEP 7.

Measuring range 6ES7-331-7KF02-0AB0 modules

You may have to change the position of the measuring range modules to suit the measurement type and range (see the chapter Setting the measuring types and ranges of analog input channels).

The necessary settings are also available on the module's imprint.

Mark the position of the measuring range module on the front door.

6ES7-331-7KF02-0AB0 Channel groups

The channels of SM 331; AI 8 x 12 Bit are arranged in four groups of two channels.

You can assign parameters only to one channel group.

SM 331; AI 8 x 12 Bit is equipped with one measuring range module per channel group.

The table below shows the relevant configuration of channel groups.

The channel group number is required to program SFC parameters in the user program.
