Photo (RV-3150 Reversible Counter)

The RV-3150 reversible counter is newly released and so helpful to measure linear displacement, angular displacement and angle dimensions in the combination with Ono RP-series rotary encoder, roller encoder, and the like, which produce two-phase 90°phase difference output signals.

The large sized LED display (14mm) is adopted so that measuring result can be read easily.

In addition, a variety of functions, such like multiple ratio selection, ratio compensation, off set , decimal point selection and counting direction, can make customer's application expanded. For data communication to an external equipment, it is available to make communication via BCD output for a sequencer, analog output for a recorder and RS-232C for a personal computer. Furthermore, comparator output can be also activated using upper and lower level setup.
