Interpolation Electronics GEL 212/213
Interpolation Electronics GEL 212
Interpolation Electronics GEL 213
General Information
- conversion of standardized sine signals into square signals up to an interpolation factor of 512
Range of Application
- interpolation of sine signals from the MiniCoder GEL 2442 K/KM/KN, GEL 243 L, GEL 295 K/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 250 mVs peak value, per track = 1 VPP as differential signal
- reference signal and inverse reference signal (option)
Output Signals
- two square-wave signals offset by 90° and their inverse signals
- reference pulse (option)
- output either with 5 V DC or 0 ... 30 V DC signal level
- with quadruple edge evaluation you can achieve a resolution of up to 2048 pulses per input signal cycle
Design
- GEL 212: 12-pole circular connector, IP 65
- GEL 213: terminal strip, IP 20

Important Note
When using the GEL 212 or GEL 213
Interpolation Electronics in combination with a
GEL 243 or GEL 2442 rail speed sensor or with a
GEL 295 rotary pulse encoder the components are
factory-adapted to each other (the Interpolation
Electronics has been labeled with the serial
number of the sensor/encoder belonging to it).
Sensors from other manufacturers are to be
adapted to the Interpolation Electronics in the
factory.
