2.6.5OME-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 consist 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 spike that often occur in industrial environments.
