The OME-DB-24P is a 24 channel
isolated digital input daughter board
for OME-PIO-D144 digital input
board. The optically isolated inputs
of the OME-DB-24P consist of a bi-directional opto-couples with a
resistor for current sensing. You can
use the OME-DB-24P to sense DC
signals from TTL levels up to 24 V.
You can also use OME-DB-24P to
sense a wide range of AC signals.
The OME-DB-24P registers a
constant logic high if the frequency
of the input AC signal is greater or
equal to 1 kHz, and if the voltage of
the AC signal is at least 4 Vrms. If
you are using an AC input signal,
you must short the AC filter jumper.
You can use the board to isolate the
computer from large common-mode
voltages, ground loops and voltage
spikes that often occur in industrial
environments.
