The module’s 20 mA backplane draw and nonisolated channel structure allow predictable I\/O density scaling when combined with other FLEX modules. Slot‑to‑slot propagation maintains stable update timing for high‑channel‑count racks, ensuring consistent scan behavior under mixed AC and DC module configurations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1794‑IA16 be installed on any FLEX terminal base A: It must be mounted on approved bases: 1794‑TB3, 1794‑TB3S, 1794‑TBN, 1794‑TB3K, 1794‑TB3SK, or 1794‑TBNK.\u003c\/p\u003e\n\u003cp\u003eQ: Are individual channels isolated A: No. Channels are nonisolated; isolation exists only between field side and system.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum on‑state voltage A: 132 VAC, with nominal operation at 120 VAC.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMaintain separation between AC input wiring and low‑level signal conductors. Verify leakage current of connected proximity switches meets the specified limits (Ileak \u0026lt; 2.5 mA, Ion ≥ 5 mA). Ensure terminal base screws are tightened according to base specifications. Avoid routing AC conductors near high‑frequency drives to reduce induced noise. Confirm environmental conditions meet vibration, shock, humidity, and contamination limits before commissioning.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48214309044414,"sku":"1794-IA16","price":860.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/allen-bradley-1794-ir8-rtd-input-module-cotybu3kvfv.png?v=1759044308","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1794-ia16-16-point-digital-input-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
