Allen-Bradley 1497-N19 Industrial Control Transformer

The Allen-Bradley 1497-N19 is a 500 VA, single‑phase control transformer with a primary rating of 240/480 VAC and a secondary that is commonly 120 VAC (with 50 Hz variants offering 110 VAC). It is designed to power control circuits in industrial automation, providing isolation and voltage conversion for relays, timers, and PLC inputs. The unit measures roughly 7 inches tall by 6 inches deep and weighs about 40 pounds, making it suitable for panel mounting in demanding industrial environments. As part of the 1497 family, the N19 configuration is a standard 500 VA control transformer used in legacy Allen‑Bradley control systems requiring 240/480 V to 110–120 V secondary conversions.
