Motrona - IV251 SSI to Analog or to Serial RS-232/485 Converts SSI Encoder Signal to Analog or to RS-232/RS-485

Model Numbers

IV 251 Converter from SSI to Analogue (Serial RS232 / RS485)


  • SSI Signal Converter suitable for use with all SSI type sensors and absolute encoders form 9 to 25 bits, either with Master mode or with Slave mode
  • Analogue outputs +/- 10V, 0-20mA or 4-20mA, 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 porcedure, or by PC
  • Free scaling, programmable linearization curves, bit blanking functions etc.
  • Power units for 115/230 VA supply
