Magnetek Resolver I/O Card PN-C79959

The Magnetek PN-C79959 is a 14-bit Resolver I/O Card designed for use in Magnetek elevator drive systems. The card interfaces resolver-based motor feedback signals with the drive control system, converting analog resolver outputs to 14-bit digital position data for precise motor speed and position regulation. A Xilinx FPGA is visible on the primary side of the board and handles high-speed signal processing. The PCB also incorporates a DDC (Data Device Corporation) RDC-19222 resolver-to-digital converter chip, confirming the 14-bit resolver conversion function. An onboard toroidal transformer provides excitation for the resolver. Relay outputs with 12VDC coils are present on the board edge, along with multiple D-sub and screw terminal connectors for field wiring. The PCB assembly mounts on a black anodized aluminum card carrier with a card-edge retention mechanism for installation in a drive chassis rack. The board was manufactured in Singapore. Serial number HAJ806SL is present on the reverse side label. The warehouse tag accompanying this item identifies the part as a 14-bit Resolver I/O Card with internal order number 14070919, dated 09/16/2024. Board dimensions are consistent with a standard drive card chassis format. Buyers should verify system compatibility with their specific Magnetek drive model prior to purchase.
