OM 621BCD
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.
