Designed for counting applications, the CPCI 307 board provides 4 stand-alone 32-bit counters for performing frequency and period measurements, counting and counting down events, and conditioning incremental (circular or linear) encoders.
Designed to operate in noisy environments, the CPCI 307 board uses differential photocoupled inputs and anti-bounce circuits.
The CPCI 307 is fully programmable using easy-to-use and powerful software. It includes :
- advanced interrupt management (18 sources),
- programmable management of counters loading and Reset-to-zero.
