104-AI12-8 PC/104 Analog Input Board, 8 channels, 12-bit resolution. Digital Input/Output: 24 parallel bits (2-8 bit ports, two 4 bit ports).

FLEXIBILITY

The following functions are available in many configurations giving the user the ability to specify exactly what inchƒs needed. Interrupts are individually or globally enabled or disabled via software. A status register is provided to determine the interrupt source.

ANALOG INPUTS

The Analog Inputs feature software programmable gain with ranges of 0-5V, 0-10V, ƒš±5V, and ƒš±10V. The configuration employs an instrumentation pre-amplifier per channel which allows for differential inputs, 200V Common Mode Rejection, high input impedance, and optional factory channel by channel pre-settable gain (1-200) to accommodate low-level inputs from sensors. Inputs 4-20mA are available as a factory-installable option.

COUNTER TIMERS

The circuit uses an 82C54 (3 sixteen bit counter/timers). The user has access to each counter/timer inchƒs gate, clock, and output signals. The output of counter two can be used to generate an interrupt. The software package supports counting events, frequency output, pulse and frequency measurement.

DIGITAL I/O

The circuit uses an 82C55A PPI with mode 0 supported. Ports A and B (16 lines) are buffered and pulled up to 5V. Port C features Change of State detection.

SOFTWARE

The package includes a setup program detailing all jumper settings. Also included are IRQ drivers, samples for DOS, and utilities for Windows operating systems (XP/2003/2008/7/8/8.1). Full register-level support for use in custom real-time or embedded operating systems.
