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 % |
