Features
- Counter series with two separate encoder inputs, each A, /A, B, /B, with individual impulse scaling (1 MHz each input channel)
- Operating modes as Single Counter, Dual Counter (independent), Differential coutner {encoder1 - encoder2} or Summing counter {encoder1 + encoder2} of two encoder positions, and many other useful counting functions
- Universal inputs TTL/HTL for any kind of impulse sources like single-channel (A only), quadrature (A/B) or differential (RS422 A, /A, B, /B)
- All models provide 4 presets with 4 fast-switchign optocoupler outputs (1 msec) and RS232 serial interface (RS485 optional)
