Maximum pulse width for
RFT9739
If the configuration applies to an RFT9739, enter the frequency pulse
width into the Max Pulse text box.
The RFT9739 frequency/pulse output operates in different modes at
high and low frequencies. At high frequencies, the output produces a
square wave with an approximate 50% duty cycle (the ON and OFF
states are of approximately equal duration). High-frequency counters
such as frequency-to-voltage converters, frequency-to-current
converters, and Micro Motion peripherals usually require such an input.
At low frequencies, the output can revert to a constant pulse width in the
ON state, with an OFF state that varies in relationship to the actual
frequency. Electromechanical counters and PLCs that have low-scan
cycle rates generally use an input with a constant ON state and a
varying OFF state. Most low frequency counters have a specified
requirement for the maximum pulse width.
The user can program the frequency/pulse output by setting the ON
state at a specified pulse width from 0.012 to 0.500 seconds to
accommodate the requirements of a particular counting device. The
programmed pulse width defines a crossover frequency:
Above the crossover frequency, the output has a 50% duty cycle. Below
the crossover frequency, the output has a constant ON state (0 V)
duration.
• The lowest available crossover frequency is 1 Hz, when the pulse
width is 0.500 seconds.
• The highest available crossover frequency is 41.67 Hz, when the
pulse width is 0.012 seconds.
Example 2:
Scaling the pulse output to represent volume flow total:
Given:
The RFT9739 frequency/pulse output represents volume total.
Problem:
Scale the pulse output so that 3000 pulses represents an
accumulated volume (a volume flow total) of 150 cubic meters.
Solution:
• Enter a value of 3000 into the Frequency text box.
• Enter a value of 150 into the Rate text box.
Since 3000/150 = 20, the frequency, or number of pulses, is 20 times
as large as the proportional flow total. Therefore, each pulse
represents a volume flow total of 0.05 cubic meters.
