The DynamicSignals/Kinetic Systems P300-343A is a 16-channel Form C relay output mezzanine card for VXIbus systems. It provides isolated SPDT relay contacts via optical isolators (LED/photo-transistor), enabling switching control in industrial automation and process control applications. The card mounts directly into Kinetic Systems V387 VXIbus modules, supporting up to four mezzanine cards for 32-channel configurable I/O. Each channel draws 5 mA to 15 mA and features programmable input filtering from 5 µs to over 1 second in 64 discrete steps. Contact closure represents logical “1.” The system supports multiple isolated input voltage versions—5 Vdc, 12 Vdc, 16 Vdc, 24 Vdc, 28 Vdc, 48 Vdc, and 120 Vac—with switching thresholds set at approximately half the rated input voltage. Integrated power-up self-test and software-initiated diagnostics provide Pass/Fail indication. Pattern recognition operates in 16-bit increments. Handshake logic is programmable with selectable external handshake support.
