Model: I-8084W
I-8084W
4/8-channel Counter/Frequency/Encoder Module
     

 

 
 
 
 
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¡¨.

Digital Input
Mode 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 £gs
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 £gs
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 %
EEPROM 128 KB
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
