    IV251*: Converter from SSI to Analogue (Voltage / Current)
    and to Serial RS232 / RS485

  • SSI Signal converter suitable for use with all SSI type sensors and absolute encoders from 9 to 25 bits, either with Master mode or with Slave mode
  • Analogue outputs +/- 10V, 0-20 mA or 4-20 mA, proportional to the encoder position
  • RS 232 and RS 485 serial interface for readout of the actual encoder position
  • Easy to set up by simple TEACH procedure, or by PC
    (for operator software see SUPPORT)
  • Free scaling, programmable linearization curves, bit blanking functions etc.
  • Power units for 115/230 VA supply: see accessories

Converter SSI-analogue-serial RS232-RS485


    IP251*: Converter from SSI to Parallel (BCD, Binary, Gray)
    and SSI to Serial RS 232

  • SSI Signal converter suitable to convert SSI data from an absolute encoder or sensor to parallel data, either with Master or Slave operation
  • Also suitable for conversion of serial RS232 data to a parallel data format
  • 25 bits parallel outputs, push-pull and short-circuit-proof, programmable output codes: Binary, Gray or BCD
  • RS232 serial link for readout of sensor data
  • Multiple facilities for scaling and linearization of parallel output data
  • Easy to set up by DIL switches or by PC (operator software: see SUPPORT)
  • Power units for 115/230 VAC supply: see accessories

Converter SSI-parallel-seral RS232


    PR210*: Converter from Parallel Data (BCD, Binary, Gray)
     to Serial Data (RS 232,  RS485)

  • Parallel data input (5 decades BCD or 20 bit binary or Gray)
  • Serial RS232 / RS485 interface for readout of the parallel data
    by means of a PC or PLC or other controls
  • This converter is ideal for combinations with other motrona units in order to  accomplish display of parallel data or conversion to other formats like analogue or PROFIBUS etc.
  • Some typical examples of combinations are shown under
     “Combinations with Converters

Converter Parallel-Serial RS232-RS485

    Please note that also some of our SSI Indicator Units are suitable for conversion
    from SSI to analogue and from SSI to serial
    (see “SSI Indicators”)


    LW 217/218*: Innovative optical fiber modules for a robust transmission of SSI encoder or sensor signals

  • The optical fibre modules LW217 and LW218 are forming together a transmission system for data transmission of SSI signals by means of optical fibres.
  • Safe and reliably  transmission of signals, up to a distance of 1500m
  • The optical fibre cable can be routed through explosive areas as well
  • Resistant against extremely strong electromagnetic fields
  • For use with all encoders and sensors equipped Synchronous Serial Interface (SSI)
  • Free adjustable SSI resolution from 1 to 99 bit
  • Maximum clock frequency 1 MHz
  • Power supply either 5 VDC or 10-30 VDC
  • Compact DIN rail mounting
  • Glass fibre cables are available ready assembled
