The BAS-762 Pulse I/O Module is designed to measure or generate pulse trains. The BAS-762 is useful for "counting" applications where the sampling rate of a discrete input module is not fast enough. The BAS-762 provides two 16-bit counter/timer channels that will accept inputs up to a frequency of 1 Mhz. Inputs are optically isolated, and compliance voltage may be up to 24VDC. When output functions are used, pulse trains up to 1 to 2 Mhz may be generated driving a load of up to 500mA. A variety of counter/timer functions are available by software configuration of the on-board processor.
The on-board processor is a 3120E2 Neuron Chip, and is used simply as a peripheral because of its rich complement of I/O models. The BAS-762 Neuron communicates with the BAS-70x processor module over the Neurowire bus (the basis of the BAS-700 I/O expansion bus). The Neuron Chip on the BAS-762 does not have a network transceiver, but does have a pin header for attaching an external transceiver for purposes of downloading new configuration software to select different modes of operation.
