  • PCI-IDI-xx Series cards offer a range of 16, 32, or 48 individual, optically isolated inputs. These cards are ideal for use in control and instrumentation applications where high-voltage protection is required. Individual channel-to-channel isolation allows every channel to be physically and electrically separated from the others.

    Inputs feature a change-of-state detection capability (denoted by a 'C' after the model number) which provides a means to automatically interrupt the host computer in real time. When one or more input bits change state, a PCI interrupt is generated to automatically wake up your application. This can greatly simplify your application program and eliminate need to continuously poll inputs.

    Each input is rectified by photo-coupler diodes, therefore polarity insensitive - either positive, negative, and AC voltage inputs are acceptable. The input range is up to 60VDC or AC rms at frequencies of 40 to 10 kHz.
