Allen-Bradley 1497-E-M4-3-N Transformer

The Allen-Bradley 1497-E-M4-3-N is a 250 VA control circuit transformer designed to convert 380/400/415 VAC utility or machine-plant power to low-voltage control signals for industrial equipment. On the primary side it supports 380, 400, or 415 VAC inputs, while on the secondary it provides two outputs—115 VAC and 230 VAC—making it suitable for powering multiple control circuits from a single source. Rated at 50 Hz, this transformer delivers isolated voltages for relays, contactors, timers, and PLC logic modules in automation panels. As part of the 1497 family, it offers a compact form factor and a robust, field-proven solution for Rockwell Automation installations in machines, conveyors, presses, and other equipment requiring a centralized, low-voltage control supply. The 0.25 kVA rating ensures enough capacity for typical control loads while maintaining space efficiency in panel enclosures.
