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)
