The module is configurable as either four analog input channels or an analog output arrangement, offering flexible AI\/AO operation for process instrumentation; each channel includes a dedicated HART modem that overlays digital information onto the 4–20 mA current loop, enabling two-wire transmitters to be read and monitored with one module. Channel wiring follows a 1+ \/ 2− for Channel I, 3+ \/ 4− for Channel II, 5+ \/ 6− for Channel III, and 7+ \/ 8− for Channel IV, all routed through the included 1719-TB8 eight-position terminal block. Designed for Ex I\/O hazardous-area environments, it supports installation in Zone 2 \/ Class I, Division 2 or safe areas, making it suitable for demanding plants where multiple HART sensors must be monitored or controlled from a single card. In typical use, it reads four 4–20 mA HART transmitters, and when configured for AO, can drive local indicators or proportional loads, delivering a compact, versatile solution for integrating HART sensors into Rockwell Automation control systems. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659010539822,"sku":null,"price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9f545f19-cac1-424a-8d18-e7e1b4595163.jpg?v=1769526603","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1719-cf4h-4-channel-hart-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
