Interpolation Electronics GEL 214

General Information

  • conversion of standardized sine signals into square signals up to an interpolation factor of 512
  • automatic offset and amplitude calibration
  • storage of the adjusted values in an EEPROM

Range of Application

  • in combination with encoders generating sine-wave signals, such as e. g. GEL 295 KN
  • interpolation of sine signals from the MiniCoder GEL 244 KN
  • interpolation of sine-shaped voltages with an amplitude of 1 Vpp

Input Signals

  • two sine-wave signals offset by 90 and their inverse signals
  • signal level 500 mVPP per track = 1 VPP as differential signal
  • reference signal and inverse reference signal

Output Signals

  • two square-wave signals offset by 90 and their inverse signals
  • reference pulse (option)
  • output either with TTL or HTL signal level

Design

  • EMC-proof metal housing, powder-lacquered black
  • 15-pole D-subminiature appliance connector for input and output
  • 12-pole circular connector (option)
