A4. DB-24P and DB-24PD Isolated Input Board
The DB-24P is a 24-channel isolated digital
input daughter board. The optically isolated
inputs of the DB-24P consist of a bi-directional
optocoupler with a resistor for current sensing.
You can use the DB-24P to sense DC signals
from TTL levels up to 24 V or use the DB-24P
to sense a wide range of AC signals. You can also use this board to isolate the computer from large
common-mode voltage, ground loops and transient voltage spikes that often occur in industrial
environments, as illustrated below. Table A4-1 is the comparison of DB-24P and DB-24PD.
