ISA sensor data aquisition card

The Model ISA-6 is a ISA bus form factor and bus compatible module that provides from one to six channels of magnetostrictive transducer interface. When commanded by the PC, the module interrogates the transducers and converts the timing information to position values. The module operates with start/stop, trailing edge start/stop, pulse width modulated or SSI transducers. Each channel can support one to thirty one recirculations or from one to 31 magnets. All operations are controlled by the host PC software. A 56 MHz oscillator provides excellent resolution even in the multi-magnet mode. The transducers are electrically isolated from the PC104 power supply. Transducer and power supply connections are made via a 37 pin DSUB connector on the rear of the board. Transducer power can be brought to the board on a 2 position screw terminal connector. The module also provides a time base that can be used by PC software to time the update of the transducers
