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.

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 % |
