Backplane bus communication velocity coordinates module execution limits up to a 63-module capacity on the internal PointBus. I\/O density scaling allows seamless expansion without violating backplane current loading limits or inducing protocol conversion latencies. Firmware flash compatibility is managed through system software tools to preserve operational baseline stability across controller updates.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Allen-Bradley 1734-AENTR Network Adapter Module\u003c\/li\u003e\n\u003cli\u003e1 x Removable Marker Carrier\u003c\/li\u003e\n\u003cli\u003e1 x Hardware Data Sheet Reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePhysical Installation Instructions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDIN Rail Mounting Mechanics\n\u003cul\u003e\n\u003cli\u003eSecure the adapter module firmly onto a standard 35 mm industrial DIN rail inside an appropriate protective enclosure.\u003c\/li\u003e\n\u003cli\u003eAlign the module slide latch and push down until it locks securely into place on the rail structure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eNetwork and Power Cabling\n\u003cul\u003e\n\u003cli\u003eConnect shielded twisted-pair Ethernet cables into the RJ-45 communication ports supporting ring or linear topologies.\u003c\/li\u003e\n\u003cli\u003eTerminate the external 24 VDC power supply lines to the removable terminal block while respecting polarity limits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Technical Inquiries\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What is the maximum number of I\/O modules supported by this adapter?\u003c\/li\u003e\n\u003cli\u003eA: The adapter supports a maximum capacity of 63 expansion modules connected along the PointBus.\u003c\/li\u003e\n\u003cli\u003eQ: What communication rates do the Ethernet ports support?\u003c\/li\u003e\n\u003cli\u003eA: The ports support 10\/100 Mbits\/s communication speeds in both half and full-duplex modes.\u003c\/li\u003e\n\u003cli\u003eQ: How is the IP address assigned to the communication adapter?\u003c\/li\u003e\n\u003cli\u003eA: IP configuration is managed using BOOTP\/DHCP utilities or physical thumbwheel switches located on the device.\u003c\/li\u003e\n\u003cli\u003eQ: Does the hardware support ring network topologies?\u003c\/li\u003e\n\u003cli\u003eA: Yes, the dual Ethernet ports support Device Level Ring (DLR) topologies for network media redundancy.\u003c\/li\u003e\n\u003cli\u003eQ: What happens if an attached I\/O module fails to respond to a request?\u003c\/li\u003e\n\u003cli\u003eA: The adapter generates an error code indicating a communication time-out back to the controller.\u003c\/li\u003e\n\u003cli\u003eQ: What is the maximum inrush current rating during startup?\u003c\/li\u003e\n\u003cli\u003eA: The maximum inrush current reaches 6 A for a duration of 10 milliseconds.\u003c\/li\u003e\n\u003cli\u003eQ: Is hot-swapping permitted for expansion modules on the active PointBus?\u003c\/li\u003e\n\u003cli\u003eA: Expansion modules can be replaced under power if supported by system architecture, but rack power rules apply.\u003c\/li\u003e\n\u003cli\u003eQ: What is the maximum field side power rating supplied through the adapter?\u003c\/li\u003e\n\u003cli\u003eA: The field side power is rated for a maximum of 24 VDC at 400 mA.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":46066399117485,"sku":"1734-AENTR","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/1734-AENTR3.jpg?v=1784730316","url":"https:\/\/www.maxwellplc.com\/products\/allen-bradley-1734-aentr-network-adapter-module-point-i-o","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
