Acting as an adapter to route PCI bus signals to and from the PMC module through the CompactPCI card slot edge connector, AcPC4620 Carrier Cards from Acromag include support for 3.3-V and 5-V DC signaling. A PLX Technology PCI6540 bridge device provides a transparent 32-bit 33/66-MHz PCI/PCI bridge for data transactions from the PCI bus (system host) to the PMC site. With an operating temperature range from -40°C to 85°C, the cards can be cooled by forced air or convection. Front and rear-panel access to field I/O signals are accommodated. The carrier cards start at $750.
