Frequency transducer for connecting NAMUR proximity sensors and sensors with NPN or PNP outputs. Configurable via DIP switch and teach-in wheel. Spring-cage connection, standard configuration. Replacement part: 2902058 MINI MCR-2-F-UI-PT.
The configurable 3-way isolated frequency transducer is suitable for the connection of NAMUR proximity sensors (IEC 60947-5-6 and EN 50227) as well as for sensors with NPN and PNP outputs that generate a frequency signal.
The measured values are converted into a linear current or voltage signal.
The device is configured via DIP switches. Alternatively, the frequency range can be configured with extended options via the teach-in wheel. The measuring transducer supports fault monitoring.
