SIMATIC S7-1500 signal modules

Scalability, performance, and usability

SIMATIC S7-1500/ET 200MP signal or periphery modules are the interface between controller and process. They can be used centrally on the SIMATIC S7-1500 CPU or in a decentralized SIMATIC ET 200MP peripheral system.

Signal modules – always the right solution for every job

Sensors enable the controller to determine current process status. The digital and analog modules provide the inputs and outputs the various actuators need to perform their tasks.

Additional highlights of the S7-1500 signal modules

More efficient monitoring – use watch and force tables via the integrated screen

  • Modules with different functions and numbers of channels 
  • Compact structure and increased functional density
  • Bus connector for self-assembling backplane bus

More efficient safety – both central and decentralized

  • Fail-safe SIMATIC S7-1500 IO/ET 200MP modules for processing standard and safety programs 
  • Functional safety to SIL 3 in accordance with IEC 62061 and PL e as per ISO 13849
Input and output modules

Find the right solution for your needs

Digital and analog input and output modules are available in many different versions to meet your needs.

Right for your needs, high-performance, and space-saving

The input and output modules feature high channel density and maximum efficiency: The minimum variation between parts makes ordering, services, and spare parts inventories much easier. 


The modules are also available in different versions to suit individual requirements. In addition to the standard modules, high-feature versions offer expanded functions and more powerful performance.


The narrow 25 mm modules with no parameterization or diagnostics are available at a particularly low price.

The perfect combination of precision and convenience

Analog input modules are designed to record process signals, such as pressure or temperature, as 16-bit digital values. Depending on the measurement type of the module, they also enable measurement of current, voltage, and resistance, and the connection of resistance thermometers and thermocouples.


Analog output modules convert a 16-bit digital value into a current or a voltage and output this to the process. They are suitable for controlling proportional valves or small servo drives. 

Compact and sophisticated

The analog SM 534 input/output module features a compact design, with four analog inputs and two analog outputs. 


The necessary shielding elements (power supply element, shielding element, shield bracket) are included in the analog input module package.
