2.7.5 DB-24P, 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. The DB-24P can be used to sense DC signals from

TTL levels up to 24 V, or use the DB-24P to sense a wide range of AC signals.

This board can also be used to isolate the computer from large common-mode

voltage, ground loops and transient voltage spikes that often occur in industrial

environments, as shown in Figure 2.9. Table 2.6 is comparison of the DB-24P

and DB-24PD.
