This Network Option Module (NOM) adds redundant Modbus Plus connectivity to a Quantum rack by providing two Modbus Plus RS485 twisted-pair ports, delivering a dual-media MB+ link for fault tolerance. As a DIO head-end adaptor, it bridges the Quantum CPU backplane to the Modbus Plus field network, enabling scalable expansion of distributed I\/O and reliable interconnection with MB+ devices within a single system. The NOM21200 is documented as part of Schneider Electric's Modbus Plus Network Modules lineup and is designed to operate alongside other Quantum MB+ modules to support robust, modular control architectures. In the broader NOM family, there are fiber-optic variants such as 140NOM25200, reflecting Schneider's offerings for different physical media while preserving the same MB+ protocol connectivity.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schneider","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283946000618,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-140nom21200-modbus-plus-module","provider":"GTG Hardware","version":"1.0","type":"link"}
