Also cataloged as O-57403-E (and 0-57403-E in some listings), it provides sixteen independently controlled AC outputs intended to switch 115 VAC loads from a PLC backplane. This module belongs to the Reliance 115 VAC High Power Output Module family, with documentation tied to the Reliance 115 VAC High Power Output Module Manual, J-3623. Distributor and repair catalogs consistently describe the 57403-E as a 115 V AC high-output module, confirming its role in legacy automation architectures that require direct AC load switching from backplane I\/O. The module’s historical designation and cross‑references appear across multiple listings, underscoring its place in older Reliance Electric AutoMax installations and related Baldor Reliance control ecosystems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"New","offer_id":51708588130606,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e8d9e7bc-af9b-451b-8f9f-e0924e2a2030.jpg?v=1770246596","url":"https:\/\/plgautomation.com\/products\/reliance-57403-e-ac-high-digital-output-module","provider":"PLG Automation ","version":"1.0","type":"link"}
