2.3.5 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 consists are bi-directional optocoupler with resistor for current sensing.
You can use the DB-16P to sense DC signal from TTL levels up to 24V 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.
