SIEMENS SM 334 analog input/output modules Product Information

SM 334 analog input/output modules

SM 334 analog input/output modules

  • Analog inputs and outputs
  • For the connection of analog sensors and actuators

Application

The analog input/output modules are suitable for the connection of analog sensors and actuators.


Design

Analog input/output modules feature:

  • 4 inputs, 2 outputs

Function

The analog input/output modules convert:

  • Analog signals from the process into digital values for the PLC and
  • Digital signals from the PLC into analog signals for the process.

The following functions are provided:

  • Input resolution:
    8 bit (6ES7 334-0CE01-0AA0)
    12 bit (6ES7 334-0KE00-0AB0)
  • Output resolution: 8 bit
  • Measuring range 0 to 10 V, 0 to 20 mA;
    the range is selected using the corresponding connections on the module.
