Channel Used: Any one of the channels can be used for Pulse
n
Output. However, the use of a particular channel for outputting
pulses will render the particular input channel unusable for either
of pulse, frequency or quadrature input.
Digital Output Type: Open Collector, 5 to 24V, 30 mA max
n
Frequency Range: 25 Hz – 10 KHz

PULSES.
Frequency Input supports:
Input Voltage: 0 V DC to 24V DC
n
ON Voltage Level: 3.0 V DC minimum
n
OFF Voltage Level: 1.0 V DC maximum
n
Input Impedance: 25K ohm
n
Frequency: 10 Hz to 100 KHz
n
Minimum Pulse Width: 500 μsec (10 Hz to 500 Hz) ; 50 μsec (10 Hz
n
to 5 KHz) ; 2.5 μsec (10 Hz to 100 KHz)
The input signal will be rejected if it is below a selected pulse
l
width.
The input signal whose pulse width is above the selected pulse
l
width must be within the frequency range specified, otherwise a
invalid value (NAN) will be shown and a fail-to-convert error
occurs.
Digital Output ON if input frequency out of range, else OFF

Quadrature Input Supports:
Channel Used: Only channel 1 and 2 can be used for quadrature
n
pulses A and B respectively. Index pulse is provided in addition.
