Digital frequency divider DFD2 and DFD2E
Application areas
APPLICATIONS : a) The correction or rationalization of the number of pulses of measuring transducers, for example a flow meter which gives 5 pulses per liter and we wish to batch in liters, or a length measuring equipment which gives 10 pulses per inch and we want to work in meters.
b) Batching : Logically if we can give one output pulse for every n input pulses we can use the DFD for batching.
Product description
The DFD has been designed to generate a series of output pulses proportional to the input pulses. The relationship between the output and input pulses is:
Io = Ii x K ;
Io = Number of output pulses ;
Ii = Number of input pulses ;
K = Correlation factor ;
The value of K is selected by means of BCD switches and jumpers inside the instrument.
Technical specifications
Operates with volumetric counter COVOL and turbine TM-44
Working conditions
The case has protection as per IP 40 and the terminals as per IP 20.
The working temperature limits are 0 to 50°C
Mains supply
The standard mains voltage is 220 V ac 50/60 Hz. AC Mains voltages of 240 V, 110 V y 24 V
50/60 Hz. and 24 V dc supply voltage are available on order. The fuse should be 250 mA slow blow (T)
The power consumption is less than 1W.
The instrument is not supplied with a mains filter and in the exceptional cases that, due to high levels of mains interference, a mains filter is needed, this must be installed externally. Due to the low power consumption, almost any small mains filter will be adequate.
Output: 5V TTL, opto isolated
