Features

I-8084W-G is a 32 bits (hardware) high speed Counter/Frequency/Encoder I/O with "Up Counter", "Frequency", "Up/Down Counter", "Dir/Pulse Counter" and "A/B Phase Counter" mode.

I-8084W-G can has variety mode combination for all 8 channels. That means it can use some channels as "Up Counter" and others as "Frequency" or "A/B Phase".

Features

Support 8 Up Counter (Minimum Pulse Width=2 μs).
Support 8 Frequency (Minimum Pulse Width=2 μs).
Support 4 Up/Down Counter (Minimum Pulse Width=2 μs).
Support 4 Dir/Pulse Counter (Minimum Pulse Width=2 μs).
Support 4 A/B Phase Counter (Minimum Pulse Width=2 μs).
Support 1~32767 (us) digital filter.
Support isolated and non-isolated input signals.
Equip with Power and Input signal LED indicators.

Applications

Counter measurement, Frequency measurement and Encoder motion control.

Counter & Frequency

4-ch Up/Down Counter (CW/CCW)
4-ch Dir/Pulse Counter (Bi-direction)
4-ch A/B Phase (Quadrant Counting)
8-ch Up Counter
8-ch Frequency

Digital Noise Filter

1 ~ 32767 μs

Isolated Input Level

On Voltage Level

+4.5 VDC ~ +30 VDC

Off Voltage Level

+1 VDC Max.

TTL Input Level

On Voltage Level

+2 VDC ~ +5 VDC

Off Voltage Level

0 VDC ~ +0.8 VDC

Minimum Pulse Width

2 μs

Input Frequency

1 Hz ~ (typically) 250 kHz (both counter mode and frequency mode)
(where 250 kHz is calculated as followings:
supposed that duty cycle = 50%, refer to Minimum Pulse Duration of High Level, we have pulse period = 2 μs x 2 = 4 μs, which is 250 kHz as a maximum)
Maximum Frequency :
refer to Minimum Pulse Duration of High Level, maximum frequency is highly affected by duty cycle
Frequency Accuracy = ± 0.4 %

Isolated Voltage

1000 Vrms

ESD Protection

2 kV (Contact for each channel)

LED Display

1 LED as Power Indicator

8 LEDs as Digital Input Indicators
