The pulse converter 6420 is designed for pulse sensors whose input frequency needs to be converted into analog output 0/4..20 mA or 0..5/10 V. The converter has an exceptionally wide frequency range 0.0003 Hz..20 kHz, so that it is ideally suited to e.g. flow sensors providing very low pulse frequencies.
Besides the current output the converter features one alarm level and a digital output. Making use of the alarm level the converter may function as a batch controller as well. Alternatively, the digital output may function as an internal configurable pulse divider/ multiplier that transmits impulses to an external counter, e.g. 1 pulse/ litre.
The converter can also be used as a pulse counter that increases the output signal according to the scaling. The counter is reset via an external contact.
The processor-based converter is easy to program by the general-purpose MekuWin PC-software or with the handheld programmer 6790.
