{"product_id":"norvi-x-di16","title":"NORVI X-DI16","description":"\u003cp\u003eThe NORVI X-DI16 is a 16-channel digital input expansion module for the NORVI X Modular Controller. It provides protected 24 V DC digital inputs for industrial switches, sensors, and logic-level signals.\u003c\/p\u003e\n\u003cp\u003eAt its core, the module integrates a PCA9555 I²C port expander, allowing the NORVI X CPU to read input states efficiently via the internal expansion bus. With four selectable I²C addresses, up to four DI16 modules can be connected on the same bus, providing a total of 64 digital inputs per controller.\u003c\/p\u003e\n\u003cp\u003eDesigned for modular scalability and DIN-rail mounting, the NORVI X-DI16 delivers reliable, noise-immune, and space-efficient 16-channel input expansion, making it ideal for industrial automation and control applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e16 × Optically isolated 24 V DC digital inputs\u003c\/li\u003e\n\u003cli\u003eBi-directional optocouplers – support both sourcing (PNP) and sinking (NPN) inputs\u003c\/li\u003e\n\u003cli\u003eOne common terminal for all sixteen inputs\u003c\/li\u003e\n\u003cli\u003ePCA9555 I²C port expander with 8 selectable addresses\u003c\/li\u003e\n\u003cli\u003eUp to 8 DI6 modules per controller (128 inputs max)\u003c\/li\u003e\n\u003cli\u003eBuilt-in over-voltage and reverse-polarity protection\u003c\/li\u003e\n\u003cli\u003eStatus LED indicators for each input channel\u003c\/li\u003e\n\u003cli\u003ePlug-and-play connection to NORVI X CPU module via expansion bus\u003c\/li\u003e\n\u003cli\u003eDIN-rail mountable industrial enclosure\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORVI Controllers","offers":[{"title":"Default Title","offer_id":51479465230657,"sku":"NORVI X-DI16","price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/4279\/5329\/files\/NORVI_X-DI16_c6a30be4-a9cf-4f74-9de4-50f76459ee1c.png?v=1773294134","url":"https:\/\/shop.norvi.lk\/products\/norvi-x-di16","provider":"NORVI Controllers","version":"1.0","type":"link"}
