n Channel Used: Any one of the channels can be used for Pulse
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.
n Digital Output Type: Open Collector, 5 to 24V, 30 mA max
n Frequency Range: 25 Hz – 10 KHz
n Duty cycle: Always 50%
n Pulse Output Duration: Selectable CONTINUOUS or NUMBERED
PULSES.
Frequency Input supports:
n 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
to 5 KHz) ; 2.5 μsec (10 Hz to 100 KHz)
l The input signal will be rejected if it is below a selected pulse
width.
l The input signal whose pulse width is above the selected pulse
width must be within the frequency range specified, otherwise a
invalid value (NAN) will be shown and a fail-to-convert error
occurs.
n Digital Output ON if input frequency out of range, else OFF
Quadrature Input Supports:
n Channel Used: Only channel 1 and 2 can be used for quadrature
pulses A and B respectively. Index pulse is provided in addition.
n Input Voltage Range: Differential: -6 VDC to +6 VDC; Single-ended:
0 VDC to 24 VDC
n ON Voltage Level: Differential: 0.2 VDC minimum; Single-ended:
3.0 VDC minimum
n OFF Voltage Level: Differential: -0.2 VDC maximum; Single-ended:
1 VDC maximum
n Common Mode Voltage: +/- 12VDC
n Input Sensitivity: +/- 200mV
n Hysteresis: +/- 50mV
n Module powered encoder: 5V DC, 0.50A
n Frequency: 200 KHz maximum
