FUNCTIONAL DESCRIPTION
The 104-IDI-48 family of boards are 48-channel PC/104 utility boards which feature 48 individually optically isolated digital inputs. They 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.
Enabled inputs feature a change-of-state detection capability (denoted by a "C" at the end of the model number) which provides a means to
automatically interrupt the host computer in real time. When one or more input bits change state, an interrupt is generated to automatically
wake up your application. This can greatly simplify your application program and eliminate the need to continuously poll inputs. Each input is
rectified by photo-coupler diodes, and is therefore polarity-insensitive - positive, negative, and AC voltage inputs are all acceptable. Zero
crossings and glitches are eliminated by input filters. The input range is up to 60 VDC or AC rms at frequencies of 40 Hz to 10 kHz.
