I-8084W-G is a 32 bits (hardware) high speed Counter/Frequency/Encoder I/O with ¡§Up Counter¡¨¡B"Frequency¡¨¡B ¡§Up/Down Counter¡¨¡B ¡§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¡¨.

|
| 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 £gs x 2 = 4 £gs, 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 = ¡Ó 0.4 % |
