Allen-Bradley 1497-D-M5-0-N Control Circuit Transformer for Bulletin 1497

The Allen-Bradley 1497-D-M5-0-N (1497-D-M5-0-N) is an industrial control circuit transformer engineered for power conversion within Bulletin 1497 control systems and industrial machinery. This unit is built to provide reliable electrical isolation and voltage regulation for sensitive control components, including contactors, relays, timers, indicators, and operator interface devices installed in motor control centers and distribution enclosures. By stepping down supply voltages to stable operational levels, it ensures safe and dependable control power distribution across industrial automation environments. The unit features heavy-duty core and coil construction suitable for demanding electrical installations, delivering consistent voltage stability under variable load conditions. The device has a net weight of approximately 10 kg, reflecting its robust industrial-grade magnetic core and winding design. Operating within standard Allen-Bradley control architectures, this transformer protects downstream equipment against electrical disturbances while sustaining continuous operations in manufacturing lines, processing facilities, and automated plant equipment. It is typically applied in motor starter panels, process control cabinets, and OEM machinery where dedicated and isolated secondary control power is necessary for system safety and operational continuity.
