It is designed to work with drop adaptors such as the 140CRA21120 and 140CRA21110 to form a multi-drop DIO topology, and the Quantum DIO architecture supports up to three head-end adaptors per CPU with network distances up to 1,800 meters per network when using repeaters. The module handles 30 input words and 32 output words, runs at 1 Mbit\/s, and draws about 4 W with a bus current of 780 mA, in the standard module format used by Modicon Quantum DIO hardware. Operating temperature ranges from 0 to 60 C (32 to 140 F), storage from -40 to 85 C, and humidity up to 95% non-condensing, with ESD and EMI protections suitable for industrial environments and typical life-cycle certifications such as UL 508 and CSA. Schneider Electric lists 140NOM21100C as discontinued for commercialization as of December 31, 2022, with end-of-life support through December 31, 2030.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schneider","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283634475242,"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-140nom21100c-dio-head-end-adaptor","provider":"GTG Hardware","version":"1.0","type":"link"}
