RATE DISPLAY:

Accuracy: ±0.01%

Minimum Frequency: 0.01 Hz

Maximum Frequency: see Max Signal Frequencies Table.

Maximum Display: 5 Digits: 99999

Adjustable Display (low) Update: 0.1 to 99.9 seconds

Over Range Display: “ ”

COUNTER DISPLAYS:

Maximum display: 8 digits: ± 99999999 (greater than 6 digits, the display

alternates between high order and low order.)

INPUTS A and B:

DIP switch selectable to accept pulses from a variety of sources

including switch contacts, TTL outputs, magnetic pickups and all

standard RLC sensors.

LOGIC: Input trigger levels VIL = 1.5 V max.; VIH = 3.75 V min.

Current sinking: Internal 7.8 KΩ pull-up to +12 VDC, IMAX = 1.9 mA.

Current sourcing: Internal 3.9 KΩ pull-down, 7.3 mA max. @ 28 VDC,

VMAX = 30 VDC.

Filter: Damping capacitor provided for switch contact bounce. Limits

input frequency to 50 Hz and input pulse widths to 10 msec. minimum.

MAGNETIC PICKUP:

Sensitivity: 200 mV peak

Hysteresis: 100 mV

Input impedance: 3.9 KΩ @ 60 Hz

Maximum input voltage: ±40 V peak, 30 Vrms

DUAL COUNT MODES:

When any dual count mode is used, then User Inputs 1 and/or 2 will

accept the second signal of each signal pair. The user inputs do not have

the Logic/Mag, HI/LO Freq, and Sink/Source input setup switches. The

user inputs are inherently a logic input with no low frequency filtering.

Any mechanical contacts used for these inputs in a dual count mode

must be debounced externally. The user input may only be selected for

sink/source by the User Jumper placement.

PRESCALER OUTPUT:

NPN Open Collector: ISNK = 100 mA max. @ VOL = 1 VDC max. VOH = 30

VDC max. With duty cycle of 25% min. and 50 % max.

PAXI SPECIFICATIONS

MAXIMUM SIGNAL FREQUENCIES TABLE

To determine the maximum frequency for the input(s), first answer the

questions with a yes (Y) or no (N). Next determine the Count Mode to be used

for the counter(s). If dual counters are used with different Count Modes, then

the lowest frequency applies to both counters.

Notes:

1. Counter Modes are explained in the Module 1 programming section.

2. If using Rate with single counter with direction or quadrature, assign it to Input A for the listed frequency.

3. * Double the listed value for Rate frequency.

4. Listed values are with frequency DIP switch set on HI frequency.

5. Derate listed frequencies by 20% during serial communications. (Placing a 5 msec. delay between serial characters will eliminate the derating.)
