Our HDI 128 digital input board features a full 2,500VDC of optical isolation for applications in industrial and laboratory settings. As a result, the host computer system stays safe from accidental damage.
The HDI 128 offers a range of input voltages from 5 to 25VDC, so it is suitable for both 12 and 24V inputs.
A built-in DIP switch on the board helps define its ID when multiple cards are installed into one PC. You can easily identify and access the board during hardware configuration and programming.
The board has dual 100-pin VDHC connectors on its bracket. Therefore, the card requires two cables and two terminal panels to accommodate all 128 input signals.
See our HDO 128 for the digital output version or our HDIO 128 for the digital input/output version of this board.
