| 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 % |
