OM 621BCD

6 digit BCD MONITOR

The OM 621BCD model is a 6 digit panel monitor of serial or parallel BCD/BIN signals and monitor of active transformer tapping lead, allowing for projection of transitional status ot servomotor running.
The instrument is based on a single-chip microcontroller, which ensures good accuracy, stability and easy operation of the instrument.

  • 6 digit programmable projection
  • input: BCD/transformer tapping lead
  • digital filters, math. functions
  • size of DIN 96 x 48 mm
  • power supply 9…50 V AC/DC nebo 80…250 V AC/DC

Options

  • excitation

  • comparators

  • data output

  • analog output
