4.9.2 Pulse and frequency output
• All outputs are electrically isolated from each other and from all other circuits.
• All operating data and functions can be adjusted.
• Passive mode:
External power supply required: U
ext
≤ 32 VDC
I ≤ 100 mA at f ≤ 10 kHz (override up to f
max
≤ 12 kHz)
• Scaling:
Frequency output: in pulses per time unit (e.g. 1000 pulses/s at Q
100%
);
Pulse output: quantity per pulse.
• Pulse width:
Symmetric (pulse duty factor 1:1, independent of output frequency)
automatic (with fixed pulse width, duty factor approx. 1:1 at Q
100%
) or
fixed (pulse width adjustable as required from 0.05 ms...2 s)
• Forward / reverse flow measurement (F/R mode) is possible.
• The pulse and frequency output can also be used as a status output / limit switch.
INFORMATION!
For further information refer to Connection diagrams of outputs on page 39 and refer to
Technical data on page 77.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
