German IPF In industrial applications, counting, increasing/decreasing pulses, measuring paths or detecting times are common task areas. However, using PLCS is not worth evaluating just one or two sensors. In this case, ipf electronic's versatile capabilities are a good choice. In addition to frequency meters, summation counters, time relays, tachometers or wear/maintenance counters, various evaluation versions are available for a variety of applications. Batch counters or summing capabilities also make more complex tasks possible. The integrated front panel can be easily used to program pre-selected values or signal evaluation modes for the operation of a linear measurement system or rotary encoder.
