Motrona - ZU252 Converts Quadrature to Analog Converts Quadrature Data from Encoders/sensors to Analog & RS-232/485

Model Numbers

Zu 252 Signal Converter from incremental quadrature count to analogue (serial RS232 / RS485)




  • The unit is suitable to convert angular and positional information from a quadrature encoder to analogue and serial format
  • Singal converter for use with al incremental encoders, proximity switches etc. either with TTL/RS422 output or with HTL (10-30V) output
  • Analogue outputs +/- 10 V, 0-20 mA or 4-20 mA, proportional to the encoder position
  • RS232 and RS485 serial interface for readout of the actual encoder position
  • Easy to set up by simple TEACH procedure, or by PC
  • Free scaling, programmable linearization curves etc. 
  • Power units for 115/230 VAC supply
