Electronic two-wire switching device for controlling wearing of brake lining in wind turbines, has sensor unit, one two-wire circuit output, another two-wire circuit output and voltage regulator for supplying sensor unit

摘要

The electronic two-wire switching device has a sensor unit (1), a two-wire circuit output (2), another two-wire circuit output (7), a voltage regulator (8) for supplying the sensor unit, and a regulator (9) and another regulator (10), which are connected to the sensor unit. The voltage regulator and the sensor unit are provided with the power by the former regulator. The two-wire circuit outputs have an antivalent switching behavior.
