M451 | Parallel I/O PMC

The M451 parallel data card is a single-width conduction-cooled (optional air-cooled) PCI mezzanine card (PMC) with a 33 MHz, 32-bit PCI interface. It provides up to 32 differential bi-directional I/O channels and up to 64 TTL I/O channels. Additional factory configurable options include up to four serial communication ports, analog current and voltage outputs and two threshold-crossing detectors. BIT stimulus and wrap-around monitoring is provided for each interface circuit. The M451 is available in both commercial and military ruggedization levels.
