The adapter provides the interface layer between FLEX Ex I\/O modules and the ControlNet network while maintaining intrinsic safety requirements for hazardous area installations.\u003c\/p\u003e\n\u003cp\u003eThe module supports Removal and Insertion Under Power (RIUP) operation, allowing maintenance activities without removing system power under supported installation conditions. Front-panel LED indicators provide status information for power supply condition, ControlNet channel health, and module communication state.\u003c\/p\u003e\n\u003cp\u003eThe ControlNet network architecture supports deterministic communication at a 5 Mbps data rate. The adapter design includes isolation between ControlNet ports and the system backplane to limit electrical interaction between network segments and connected I\/O assemblies.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What type of I\/O modules can be connected to the 1797-ACNR15\/C adapter?\u003cbr\u003eA: The adapter interfaces with FLEX Ex I\/O modules and supports connection of up to 8 FLEX Ex I\/O modules within the configured system assembly.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1797-ACNR15\/C support redundant communication paths?\u003cbr\u003eA: Yes. The module provides dual ControlNet coaxial ports identified as Channel A and Channel B for redundant ControlNet media connections.\u003c\/p\u003e\n\u003cp\u003eQ: Can the adapter be removed while the system remains powered?\u003cbr\u003eA: The module supports RIUP (Removal and Insertion Under Power) functionality when installed according to the applicable hazardous area system requirements.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 1797-ACNR15\/C in a suitable enclosure according to hazardous location requirements. Verify that the enclosure provides the required environmental protection because the module uses an open-style construction.\u003c\/p\u003e\n\u003cp\u003eUse approved ControlNet coaxial cabling with correct BNC termination practices for Channel A and Channel B connections. Maintain cable separation from high-voltage power conductors and sources of electrical noise.\u003c\/p\u003e\n\u003cp\u003eConnect DIN rail or panel mounting hardware securely before wiring the module. Confirm supply polarity and voltage range before applying 24 VDC power. Maintain proper grounding and bonding practices for the enclosure and associated control system.\u003c\/p\u003e\n\u003cp\u003eFor intrinsically safe installations, follow the applicable ATEX, IECEx, FM, and local hazardous area wiring requirements. Do not modify field wiring methods or component combinations outside the approved system configuration.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43787557797978,"sku":"1797-ACNR15\/C","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1797-ACNR15C2.jpg?v=1785909963","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1797-acnr15-c-flex-ex-controlnet-coaxial-adapter-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
