DB-16P Isolated Input Board
The DB-16P is a 16-channel isolated digital input daughter board. The optically isolated inputs of the
DB-16P are consisted of are bi-directional optocoupler with resistor for current sensing. You can use
the DB-16P to sense DC signal from TTL levels up to 24 V or use the DB-16P to sense a wide range of
AC signals. You can use this board to isolate the computer from large common-mode voltage,
ground loops and transient voltage spike that often occur in industrial environments.
