The existing ND 221B to 281B series will be superseded by two newly developed models. The ND 280 beginner model basically has the same features as the ND 221B. The modular ND 287 position display supersedes the ND 281B in its basic configuration. The functions of the ND 231B can be made available with a second encoder module. A convenient graphic user interface and comprehensive software functions expand the possibilities of use of the ND 287, up to and including SPC. Optional analog sensors can be connected, as well. Encoders with EnDat 2.2 interface can be connected to both position display units.
