Schneider Electric SE 9070EO17D2 1-Phase Transformer

Schneider Electric’s Square D 9070EO17D2 is a compact 25 VA, 1‑phase control transformer that converts 240/480 VAC from the mains to a 24 VAC secondary for low‑voltage control circuits. Designed for 50/60 Hz operation, it’s ideal for powering relay coils, contactors, PLC inputs, and signaling devices inside electrical control panels while providing electrical isolation between mains voltage and control circuitry. The EO17D2 model packs a small footprint—2.50 in high by 3.00 in wide by 3.31 in deep—allowing installation in tight panel spaces or enclosures typical of industrial automation installations. This transformer is part of Schneider Electric’s EO family of industrial control transformers, delivering a reliable 24 VAC output suitable for 24 V coils and sensors in control circuits. Applications include panel‑mounted control circuits in manufacturing lines, HVAC control panels, and process automation where a dedicated 24 VAC supply from a 240/480 VAC source is required. With a 25 VA rating and 50/60 Hz compatibility, the 9070EO17D2 provides the necessary current for multiple low‑power loads in a single compact unit.
