{"product_id":"allen-bradley-1734-ia4-digital-ac-input-module","title":"Allen-Bradley 1734-IA4 Digital AC Input Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1734-IA4 is a POINT I\/O digital input module that provides four 120 V AC, non-isolated, sinking input channels. Each channel accepts standard 120 VAC input signals from devices such as switches or sensors, with a common return shared across all four inputs. The module requires an external 120 V AC power supply (nominal 120 V, 60 Hz; operating range 85–132 V, 47–63 Hz) and communicates with the POINT I\/O bus via the POINTBus, drawing up to 75 mA at 5 V DC. Power dissipation is up to 0.50 W at 132 V AC; isolation voltage is not specified for field-to-bus on this non-isolated IA4 variant. For mounting, the IA4 is open style and designed for DIN mounting with bases such as 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS. Module dimensions are 2.21 in. long × 0.47 in. wide × 2.97 in. high and it weighs about 1.09 oz. The four inputs are non-isolated and configured as sinking inputs, making this module suitable for reading discrete 120 VAC signals in a Rockwell Automation control system via the POINT I\/O network.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659004313902,"sku":null,"price":1740.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fccd3e8c-9247-4ae7-9a12-e82716671177.jpg?v=1769526501","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1734-ia4-digital-ac-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
