1. 1. About the NuDAM Counter/Frequency Modules
The NuDAM provides a counter / frequency input module, which has
two 32 bit counter input channels with built in programmable timer
for frequency measure function.

1. 2. Overview of NuDAM-6080
What is NuDAM-6080?
ND-6080 is a counter / frequency input module. It has two 32-bit
counter input channels with built in programmable timer for
frequency measurement and supports both photo isolated and
non-isolated input mode. The maximum counting value is
4,294,967,295 for counter input channel and the frequency-input
range is from 1 Hz to 100 kHz. A programmable digital filter can
be enable for both high and low level minimum signal width to
reduce noise spike. Besides the programmable threshold for non-
isolated input can further reject noise on the input signal level.
The module provides the counter comparator or the alarm
function. The alarm limit of two counters can be set independently
by programming. The alarm status can be send to digital output
channels if this function is ON. The supervisor of a factory can
‘see’ or ‘hear’ the alarm if the digital output channel control a real
alarm device. The two digital output channel can be set for
general purpose used if the alarm is disable. For example,
connecting relay devices to DO channels, the NuDAM-6080 can
be used to control the high power devices.
