Retransmit Pulse Output (RETRAN)
The retransmitting pulse output will send an output pulse for every input pulse, essentially
duplicating the input signal. The output will generate a pulse at the falling edge of every
input pulse.
No additional programming is required for a retransmitting pulse output.
Quadrature Pulse Output (QUAD)
The pulse output set to quadrature will duplicate the other open collector output, but lag
by ¼ duty cycle (90 degrees out of phase). For example, Out 1 will follow Out 2, if Out 1
is set to QUAD. Only one output should be set to QUAD. If both outputs are set to QUAD,
both outputs will be disabled. The other output should be programmed as desired for the
quadrature output function, and must be a pulse (PUlse) output selection.
Test Pulse Output (test)
The test output setting programs the output to generate pulses at a programmed constant
frequency. Set the frequency decimal point location in the DECPT menu, and then enter
the desired output frequency in Hz in the PULSE menu.
Modbus PV or Math Pulse Output (PV)
The pulse output may be based on an enabled Modbus PV or math channels CV1 to
CV4. The pulse output frequency in hertz (Hz) is calculated as the value of the selected
PV or CV divided by the programmable count (or divisor).
The frequency of the pulse output will update as the PV or CV value is changed.
For example, if the output is set to reference PV 2, and PV 2 is reading 1540.5, with a
count or 10, the pulse output frequency will be 154.05 Hz.
