Allen-Bradley 1497-N16 Control Circuit Transformer

Allen-Bradley 1497-N16 Control Circuit Transformer is a 130 VA single‑phase device that steps down higher-m voltage mains to a 120 VAC control supply for relays, contactors, timers, and PLC input circuits in industrial environments. It features multi‑tap primaries for worldwide voltages: 240/480 VAC input at 60 Hz with a 120 VAC secondary, and 220/440 VAC input at 50 Hz with a 110 VAC secondary. This makes it suitable for international machine controls and OEM panels that require a stable 120 VAC control rail. As part of Allen-Bradley’s Bulletin 1497 family of Global Control Circuit Transformers, the 1497‑N16 is designed to deliver reliable control voltage within its 130 VA rating, enabling robust operation of control circuitry in typical industrial loads. Common applications include powering relay coils and logic circuits inside control cabinets, panels, and automation equipment where a 120 VAC secondary is used to drive low‑voltage control circuitry from higher‑voltage mains.
