2.5.5OME-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.
