The 5I25 low-cost, low-profile programmable industrial I/O card for the PCI bus uses standard parallel-port pinouts/connectors for compatibility with most motion control or CNC breakout cards and step motor drives. It provides a motion-control performance boost while retaining a reliable real-time PCI interface. Each I/O bit in the card’s parallel port has programmable direction and function.
Open-source FPGA firmware configurations are provided for hardware step/dir generation, PWM generation, servo control, absolute and incremental encoder counting, real-time remote I/O, event counting, and high-speed serial communication. ($64 ea/100 — available now.)
