OME-DB-24PD Isolated Input Board
The OME-DB-24PD is a 24 channel isolated digital input daughter board. The
optically isolated inputs of the OME-DB-24PD consist of a bi-directional opto-
coupler with a resistor for current sensing. Use the OME-DB-24PD to sense DC
signals from TTL levels up to 24V or use the OME-DB-24PD to sense a wide range
of AC signals. Use this board to isolate the computer from large common-mode
voltages, ground loops and transient voltage spikes that often occur in industrial
environments.
