Integrated high-speed backplane bus communication velocity allows cycle times down to sub-millisecond ranges while serving as the primary power and data head for up to 64 active RSTi-EP slice I\/O modules. The internal bus repeater stabilizes logic voltage rails and decouples network jitter from field I\/O expansion slices.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the EPXPNS001 support hot-swapping of downstream I\/O modules on the RSTi-EP bus?\u003c\/p\u003e\n\u003cp\u003eA: Yes, downstream RSTi-EP I\/O modules can be replaced under power without interrupting PROFINET bus traffic or power pass-through running via the network adapter module.\u003c\/p\u003e\n\u003cp\u003eQ: What network topologies are natively supported by the dual RJ-45 Ethernet ports on the EPXPNS001?\u003c\/p\u003e\n\u003cp\u003eA: The integrated two-port Ethernet switch supports Line, Star, and Ring network topologies, including Media Redundancy Protocol (MRP) for deterministic network recovery.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eSnap the EPXPNS001 network adapter onto a standard 35 mm DIN rail (TH35) before locking adjacent I\/O expansion slices into place.\u003c\/li\u003e\n\u003cli\u003eConnect the primary 24 VDC system power feed to the front-facing push-in spring terminals, ensuring correct polarity (20.4 to 28.8 VDC operating range).\u003c\/li\u003e\n\u003cli\u003eInsert industrial-grade Category 5e\/6 shielded Ethernet cables into ports X1 and X2, verifying that the connector latch clicks securely into the RJ-45 housing.\u003c\/li\u003e\n\u003cli\u003eTerminate the DIN rail directly to Functional Earth (FE) using low-impedance grounding straps to establish shield continuity for high-frequency noise rejection.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":48707587866814,"sku":"EPXPNS001","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/EPXPNS001_3_35b28ead-061a-4b28-be7d-6e41380554b2.png?v=1786609067","url":"https:\/\/www.autooiltech.com\/products\/emerson-epxpns001-pacsystems-rsti-ep-network-adapter","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
