Schneider Electric 9070EO4D1 Industrial Control Transformer

Schneider Electric's Square D 9070EO4D1 is a chassis‑mount EO‑type industrial control transformer that furnishes dependable control power by converting 240/480 VAC line power to 120 VAC for control circuits. Rated at 300 VA and configured for 1‑phase operation, it features dual primary windings that accept either 240 VAC or 480 VAC input and a 120 VAC secondary. With an 80°C rise rating, it is designed for continuous‑duty service in panels, control cabinets, and equipment where compact form factor and stable voltage are essential. The 9070EO4D1 belongs to Schneider Electric’s 9070 EO family, which is noted for tight voltage regulation and low temperature rise, contributing to reliable performance in relays, contactors, timers, and PLC I/O applications. As a standard Square D product, it’s compatible with industrial control systems that require a dedicated control transformer to isolate and power low‑voltage control logic from high‑voltage mains.
