2.6.5 OME-DB-24P/24PD Isolated Input Board
The OME-DB-24P is a 24 channel isolated digital input daughter board. The
optically isolated inputs of the OME-DB-24P, consists of a bi-directional opto-
coupler with a resistor for current sensing. You can use the OME-DB-24P to sense
DC signal from TTL levels up to 24V or use the OME-DB-24P 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 spikes that often occur in industrial
environments.
