Asea Brown Boveri Limited O-48664-2 Transducer

ABB 0-48664-2 / O-48664-2 Voltage Transducer is a legacy transducer board used in Reliance Electric drive systems and older ABB/Brown Boveri drive architectures. The module features a central transformer (TR-11805, 69000-34-R) mounted in a frame and screw-mounted to the board, with a ten-position screw-terminal strip along the leading edge for interconnection. This construction yields an isolated voltage sensing interface that feeds the drive's control electronics. The 0-48664-2 designation appears across multiple parts catalogs and is described in listings as a voltage transducer board used inside drive assemblies; third-party sources list it as discontinued by the manufacturer. In practice, it appears in used, surplus, or refurbished form through distributors and marketplaces that specialize in obsolete ABB/Reliance components. Typical applications include older motor-drive installations requiring a compatible voltage transducer module to interface with control logic and feedback within vintage drive systems; the part is commonly encountered in legacy drive repairs and replacement projects aimed at maintaining compatibility with legacy control panels and drive architectures.
