Designed to operate within DeviceNet industrial communication networks, this 24 VDC block expansion module provides reliable signal data collection for distributed machine control architectures. It features sixteen sinking digital inputs grouped for efficient industrial automation system integration.\u003c\/p\u003e\n\u003ch3\u003eInput Channel Architecture\u003c\/h3\u003e\n\u003cp\u003eThe module features sixteen discrete input channels configured for sinking signals operating at a nominal 24 VDC. These inputs are organized into two groups of eight channels to facilitate logical separation and wiring management. It efficiently processes field device status while maintaining high noise immunity in demanding industrial environments.\u003c\/p\u003e\n\u003ch3\u003eNetwork Communication and Power\u003c\/h3\u003e\n\u003cp\u003eOperating over the DeviceNet network protocol, the unit enables seamless data exchange using polled, cyclic, or change-of-state messaging. It receives operational power directly through the network architecture, minimizing external wiring requirements and streamlining cabinet layouts for distributed control setups.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1791D-16B0X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley (Rockwell Automation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCompactBlock I\/O Expansion Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocol\u003c\/td\u003e\n\u003ctd\u003eDeviceNet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003e16 Digital Inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Type\u003c\/td\u003e\n\u003ctd\u003eSink\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Operating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.55 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifecycle Status\u003c\/td\u003e\n\u003ctd\u003eDiscontinued by Manufacturer (June 29, 2013)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary function of the 1791D-16B0X module?A: It functions as a 16-point discrete expansion input module designed to gather sinking 24 VDC sensor signals on a DeviceNet network.\u003c\/p\u003e\n\u003cp\u003eQ: How are the input channels organized on this expansion block?A: The sixteen input channels are arranged into two separate groups of eight channels to support structured field wiring.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53056670204184,"sku":"1791D-16B0X","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1791D-4B4P_Cocoai_15acae24-8579-46fb-ab92-53f3fc84843b.jpg?v=1793066966","url":"https:\/\/www.innoplcsync.com\/products\/i-o-expansion-modules-allen-bradley-1791d-16b0x","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
