Pt micro combi converter

Electronic device technology / converter

PT micro combi converter

The converter analyses a Pt sensor and outputs the equivalent KTY resistance. A Pt sensor can therefore be operated on evaluation electronics for KTY sensors.

Pt1000-KTY84 converter kit for Siemens SME120/125

Plug & Play adaptor for Siemens drives:
Adaptation of the Pt-KTY converter to Siemens SME120/125 using a kit consisting of a signal processing unit on SME connection X200 (encoder line) and a unit for voltage tapping on X100.


  • Compliance with EMC conformity
  • Protection class IP 67 (as per SME120/125)
  • Electrical connections are established with standardised circular connectors M23 (X100), M17 (X200) and M12
  • Aluminium housing
  • Dimensions 46x25x128 mm (SIG) and 42x25x114 mm (TAP)

Operation of motors or generators with Pt sensor especially for Siemens SINAMICS systems with external sensor module SME120.

The converter analyses the resistance of a Pt100 or Pt1000 sensor and converts it into equivalent KTY sensor resistance. This eliminates the need for the user to replace frequency converters and control and evaluation devices that are tuned to the signal of a KTY sensor. At the output of the converter, the resistance of a potentiometer is set according to the measured temperature. The converter with connected Pt sensor can therefore replace a KTY sensor.

  • Enables thermal machine protection of new motors with Pt1000 sensors in existing Siemens SINAMICS S120 drive systems
  • Extends the system service life
  • Maintenance-friendly as a pure plug & play installation requiring no prior electrical engineering knowledge
