Designed for Zone 2\/Class I, Division 2 environments, it interfaces with standard 1719 Ex I\/O backplanes and ships with a 1719‑TB6 6‑pole screw‑terminal block for field wiring. This intrinsically safe counter module integrates into compact modular I\/O configurations, enabling accurate speed or rate monitoring of rotating equipment in chemical plants, offshore facilities, and other installations requiring safety‑rated equipment. Being part of the 1719 Ex I\/O family, it follows the same installation practices and backplane integration as other Ex I\/O modules, simplifying wiring, maintenance, and module exchange in demanding environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659010343214,"sku":null,"price":834.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5be7b2b1-0aa5-4384-b4b0-970e84306be5.jpg?v=1769526600","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1719-ij-counter-module","provider":"PLG Automation ","version":"1.0","type":"link"}
