Minimum DC operating voltage is 97V, so it does not work with 24V signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What does the On-state voltage range mean for my application?\u003c\/strong\u003e\u003cbr\u003eA: It means the module reliably detects an ON condition between 87-138V AC or 97-138V DC. Voltages below these thresholds may not register correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Can I replace the module without rewiring?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Disconnect the \u003cstrong\u003e1771-WA\u003c\/strong\u003e wiring arm, replace the \u003cstrong\u003e1771-IA\u003c\/strong\u003e module, then reattach the arm. Your existing field wiring stays intact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is the maximum input current?\u003c\/strong\u003e\u003cbr\u003eA: At 120V AC 60Hz, the typical input current is 7.9mA. At 125V DC, it is 7.4mA. The module limits current internally.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Do you ship internationally, and what is the return policy?\u003c\/strong\u003e\u003cbr\u003eA: Yes, we ship worldwide via FedEx, UPS, or DHL. We offer a 30-day return window for this \u003cstrong\u003e1771-IA\u003c\/strong\u003e module in its original condition.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin-top: 2em;\"\u003e\u003cstrong\u003eContact Information Inquiries:\u003c\/strong\u003e \u003ca href=\"mailto:sales@nex-auto.com\" style=\"color: #0d47a1;\"\u003esales@nex-auto.com\u003c\/a\u003e | \u003ca href=\"https:\/\/wa.me\/8615392429628\" rel=\"noopener\" style=\"color: #0d47a1;\" target=\"_blank\"\u003e+86 153 9242 9628\u003c\/a\u003e (WhatsApp)\u003cbr\u003ePartner: \u003ca href=\"https:\/\/www.nex-auto.com\/\" rel=\"noopener\" style=\"color: #0d47a1;\" target=\"_blank\"\u003eNexAuto Technology Limited\u003c\/a\u003e\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45760576913569,"sku":"1771-IA","price":236.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/5390\/3265\/files\/1771-IA.jpg?v=1772011793","url":"https:\/\/www.autonexcontrol.com\/fr\/products\/allen-bradley-1771-ia-plc5-discrete-input-module-120vac","provider":"AutoNex Controls Limited ","version":"1.0","type":"link"}
