SIEMENS SIMATIC S7-300 – 6ES7331-7KB02-0AB0


The SIMATIC S7-300 is used in many applications worldwide and has been proven successful millions of times. The SIMATIC S7-300 universal Controllers saves on installation space and features a modular design. A wide range of modules can be used to expand the system centrally or to create decentralized structures according to the task at hand, and facilitates a cost-effective stock of spare parts. SIMATIC is known for continuity and quality.

  • Analog inputs
  • For connection of voltage and current sensors, thermocouples, resistors and resistance thermometers


Analog input modules allow the connection of the PLC to analog signals of the process. They are suitable for connection of voltage transmitters and current transmitters, thermo elements, resistors and resistance thermometers.


The analog input modules convert analog signals from the process into digital signals for internal processing in the PLC.

The modules feature:

  • Resolution from 9-bit to 15-bit + sign (with different conversion times), can be parameterized.
  • Different measurement ranges;
    the default setting of the current/voltage ranges is set mechanically using measuring range modules, the fine adjustment is performed with STEP¬†7 “Hardware configuration” via PG.
  • Interrupt capability;
    the module sends diagnostic and limit-value interrupts to the CPU of the PLC.
  • Diagnostics;
    the module sends extensive diagnostic information to the CPU.
