Pulse signal converter6420

digital analog DIN rail

f/I/U Pulse converter 6420 • Frequency conversion in the range 0.0003 Hz..20 kHz • Sensors NPN, PNP, Namur, pickup or contact • Alarm level or pulse divider/ multiplier • Output 0..20 mA, 4..20 mA, 0..5 V or 0..10 V • Output linearisation • Adjustable digital input filter • Pulse counter with analog output (optional) • Configuration by PC software or hand held programmer • Power supply 24 VDC 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.
