The KUSB-3160 module provides 96 digital lines, 64 I/O and 32 input, grouped into twelve 8-bit ports. Eight ports are either input or output with four ports dedicated as inputs. Digital outputs are capable of driving external solid-state relays (12mA sink). The KUSB-3160 can generate an interrupt when any of the 8 digital I/O lines corresponding to ports 1 or 2 changes state. This feature is useful when you want to monitor critical signals or when you want to signal the host computer to transfer data to or from the board. You can enable the interrupts on a bit-by-bit basis on this port. All signals are brought out to a dedicated, standard 100-pin connector on the backplate of the KUSB-3160 module. The KUSB-STP100 screw terminal panel and KUSB-CABDIO are available to simplify connections. The 500V isolation barrier protects your computer and ensures a reliable stream of data.
