NOTE
To comply with the EMC standards, use shielded cables in signal inputs (ground the shield in the panel only
in one side of the cable) and cables less then 30 meters for power source inputs.
IMPORTANT
This module has 12-bit counters to accumulate up to 4096 pulses, for each one of 16 channels, before a
overflow occurs. Therefore, considering the maximum operation frequency, it has the following minimum
overflow time:
• M-304: 4096 pulses / 10000 Hz = 0,4096 s
The system macro-cycle must be lower than the pulse counter module overflow time.
