ipf electronic´s WD57 and/or WS57 rotation speed pilot switches and zero speed monitors are characterized by simple ease of use and reliability. With these units it is possible to not only monitor speed and idleness, but also direction of rotation, i.e. when a multi-track rotary encoder is connected. 3 relays with a change-over contact serve as an output. In addition, there is an analog output (voltage / current). The monitor is programmed via 4 buttons, a two line LCD display visualizes the information. The data can be read off via a serial interface. The housing is suitable for snap-on to a top-hat rail.
