1 Universal Frequency Transducer TERFACE Data Sheet 000_en_0 PHOENIX CONTACT - 0/00 Description, the programmable MCR frequency transducer, is a module for displaying and converting frequencies up to0 khz. On the input side, all common frequency generator signals in, and -wire technology, and signals from incremental encoders can be collected. The input impulses are evaluated using period measurement and are then output by a processor as an analog voltage or current value to match the measuring range start and end value entered. In order to achieve as short as possible reaction times, the inputs of the frequency transducer have purposely been designed without a frequency input filter. An automatic measurement range selection function (autorange) ensures that the measured value is always displayed with the optimum resolution. Frequency interferences can, however, lead to too large a division factor being selected for low input frequencies. This in turn can result in an erratic output signal (see "Operation with Disturbed Frequency Signals" on page ). In order to stabilize fluctuating input values, a filter function has been implemented for conversion into the analog output value. The depth of this filter can be set from to using the membrane keyboard. The optimum filter depth depends on the application. In addition to the analog output, there is also a transistor switching output with a maximum carrying capacity of 00 ma, for monitoring functions, for example (not short-circuit proof). Specially for rotational speed measurement, it is possible to both enter the measuring range start and end value in revolutions per minute (RPM), and to observe the revolutions in RPM on the LCD (-pos. RPM as unit) during operation. Make sure you always use the latest documentation.
