Frequency Converters

Frequency converters repeat and convert the input frequency from a variety of hazardous area signals (mechanical contact, proximity sensor, magnetic pick-up, voltage or current level) into the safe area. The input signal is repeated on an isolated open-collector transistor output and also converted into an analog output signal proportional to the input frequency.

Monitoring for frequency alarms and fault detection is provided by the relay output and fault bus output. The analog output can be selected as current sink or source or as voltage with two different voltage ranges. The device can be adjusted by means of DIP switches or the operation software program PACTware™. The intrinsically safe input is per EN 50020 safely isolated from the output and the power supply.
