ADAM-4080 Counter/Frequency Input Modules
ADAM-4080 Counter/frequency input module has two 32-bit counter input channels
(counter 0 and counter 1) with built-in programmable timer for frequency measure
-
ment. These cost-effective modules let you monitor counter/frequency data as mea
-
surements are taken.
Signal Input Mode
The ADAM-4080/4080D provides separate terminals for photo isolated input and
non-isolated input to simplify the wiring. Optoisolated input provides 2500 V
RMS
iso
-
lation to protect your equipment from power surges at the ground terminal. After you
make the physical connections, program the module to identify which of its two input
terminals should be activated (isolated or non-isolated terminals).
Programmable Digital Filter
The ADAM-4080 module includes a unique programmable digital filter to reject noise
from the input lines. You can specify separate time constant like minimum signal
width at high level and minimum signal width at low level. This provides stable output
readings.
Programmable Threshold
When the ADAM-4080 is programmed for non-isolated input, you can set a high and
low trigger level. Like the programmable digital filter, the programmable threshold
rejects noise from the input lines and provides a stable input readings
External Control (Gate mode)
Aside from the GND and counter terminal, each channel has a gate terminal to con
-
nect to an external gate signal. The gate signal (high or low) can trigger the counter
from start or stop counting. The gate mode can be among these three options, low,
high or disabled (low means that counting starts when the gate signal is low. It stops
once the gate signal becomes high)
Programmable Alarm Output
The ADAM-4080 module provides a configurable alarm for each counter. When the
counter reaches an alarm limit, it will trigger the built-in digital output of machine ON/
OFF control. The alarm limits may be downloaded into the module's EEPROM by the
host computer. The initial count value of ADAM-4080 module's counter can be con
-
figured in any values.
The alarm functions can be enabled or disabled remotely. When the alarm functions
are enabled, digital output channels are used to indicate the alarm states. For ADAM-
4080, digital output channel 0 equals to the alarm state of counter 0, and digital out
-
put channel 1 equals to the alarm state of counter 1.
Every A/D conversion will be followed by a comparison of alarm limits. If the input
value exceeds one of these limits, the corresponding alarm state is set to ON.
There are two alarm mode options, momentary and latching, for ADAM-4080D. If the
alarm is in latching mode, the alarm will stay on even when the input value returns
within the limits. An alarm in latching mode can be turned off by issuing a Clear Alarm
command from the host computer. A latching alarm is cleared by the module when
the opposite alarm is set. For example, the alarm is in latching mode and the high
alarm is then turned ON. When the module receives a value that is lower than the low
alarm limit, it will clear the high alarm and turn the low alarm ON.
