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”.
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 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 %
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
