Before energizing, connect an external power supply providing 24 VDC nominal (acceptable range 19.2…31.2 VDC). Use stranded copper wire sized 0.34…2.5 mm² (22…12 AWG) rated at 75 °C (167 °F) or higher, with insulation thickness not exceeding 1.2 mm (3\/64 in.). For Ethernet connections, use RJ45 Cat.5 cables. Configure the IP address, optional gateway, and subnet mask before placing the module into service. Do not install or remove the module while powered.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe 1794-AENTR requires minimal routine maintenance. Periodically inspect the DIN rail mounting and ensure all connections remain secure. Monitor the status indicators—Module, Network, Link1, and Link2—to quickly identify communication issues. The module’s robust design tolerates vibration up to 5 g and shock up to 30 g, ensuring long-term reliability in harsh industrial settings. Regular checks of the power supply voltage and network cabling will help prevent unexpected downtime.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe 1794-AENTR is part of the Allen-Bradley Flex I\/O family and communicates using the EtherNet\/IP protocol. It integrates seamlessly with Rockwell Automation controllers such as ControlLogix and CompactLogix. The module supports linear and ring topologies, with no network scheduling or routing tables required, simplifying integration into existing architectures. It can interface with up to eight Flex I\/O modules on the same DIN rail, providing scalable I\/O expansion.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting the 1794-AENTR, verify that your control system supports EtherNet\/IP and that the required number of I\/O modules does not exceed eight. Confirm the power supply voltage matches the 24 VDC nominal requirement. For assured quality and availability, consider purchasing from PLC Source PRO, a trusted supplier of industrial automation spares. Ensure you have the necessary RJ45 cables and DIN rail mounting hardware for installation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default","offer_id":44454012780643,"sku":"1794-AENTR","price":230.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/1794-ACN15_202_4098430b-7feb-4aa0-a5cf-d5a56aaf6cc2.jpg?v=1786116673","url":"https:\/\/www.plcsourcepro.com\/ar\/products\/1794-aentr-industrial-automation-module-by-allen-bradley","provider":"PLC Source PRO","version":"1.0","type":"link"}
