Figure 3-71 ADAM-4080D Counter/Frequency Input Module
with LED Display
Channels: 2 independent 32-bit counters (counter 0 and counter 1)
Input frequency: 50 kHz max.
Input mode: Isolated or non-isolated
Isolation input level:
- Logic level 0: +1 V max
- Logic level 1: +3.5 V to +30 V
- Input Impedance: 1.2 kΩ
Non-isolation input level (programmable threshold):
- Logic level 0: 0 to +5V (default = 0.8 V)
- Logic level 1: 0 to +5V (default = 2.4 V)
- Input Impedance: 50 MΩ
