The AW-Lake FAC-1 Frequency to Analog Converter is used to convert frequency inputs from speed sensors into a linear analog signal. The output signal can be set for the typical test and control ranges of 0 – 20 mA, 4 – 20 mA or 0 – 10 V. All configuration is performed via supplied software or can be pre-configured by factory upon order.

Optimized for control and monitoring applications in drive, system and process engineering, the FAC-1 converter can convert a wide variety of signals from rotational speed sensors, rotary pulse encoders or proximity switches. It can process NPN, PNP, push-pull or TTL outputs, as well as sine wave signals from tacho generators and passive sensors. The normalized signal provided by the FAC-1 converter means it can be easily connected to PC or SPS controllers, recorders or indicators.

Standard Output signal

The output signal is user-set via PC software to fit the respective measuring job. The output is then scaled to the MIN and MAX frequency range set in the paramters (see below). After programming an additional final adjustment of +/-10% can be done via the front panel

User-Set Parameters Output: 0...20mA or 4...20mA or 0...10VDC Max. Frequency: 25...18.000Hz Min. Frequency: 0...50% of max. frequency in Hz

Period Count: 1...254 impulses per revolution Max. Measuring time: 100...5000ms Time Constant T1: 0...5000ms
