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. These cards are especially useful in applications where high common-mode external voltages are present. Isolation is required to guard electronics from transient voltage spikes and offers greater common-mode noise rejection in electronically noisy surroundings containing industrial machinery and inductive loads.
