It uses two copper RJ-45 ports for network access and supports up to 128 TCP connections, enabling numerous concurrent I\/O and messaging operations. Designed to mount in a ControlLogix chassis, the EN3TR bridges the backplane to the Ethernet\/IP network, supporting standard EtherNet\/IP data exchange for I\/O and explicit messaging. The module carries a continuous isolation rating of 30 V and uses basic insulation between the Ethernet network and the backplane, with type testing up to 980 V AC for 60 seconds for safety. Typical power characteristics include about 5.1 W of dissipation, a 1 A draw at 5.1 V, and about 3 mA at 24 V, reflecting the module’s modest on-board power needs in industrial environments. Operating temperature is 0 to 60 °C, making it suitable for many factory floor applications, including high-speed PLC-to-device communication for remote I\/O, HMIs, servo drives, and distributed control systems via EtherNet\/IP.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657381314862,"sku":null,"price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9e32a9fd-faab-47a0-92ae-2ddb6b23aa13.jpg?v=1769468388","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-en3tr-ethernet-ip-network-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
