This module serves critical industrial automation roles by accurately measuring fast pulse trains and incremental encoder signals, converting them into digital values for process controllers. It interfaces directly with the S800 I\/O modular system via ModuleBus, allowing flexible placement and hot-swapping capabilities in demanding continuous and batch process environments.\u003c\/p\u003e\n\u003cp\u003eEngineered for precision data acquisition, the DP820 supports RS-422 differential signaling to ensure high noise immunity and reliable signal transmission over longer cable runs. It is commonly deployed in flow measurement, rotational speed monitoring, and position tracking applications where exact pulse counting is vital to process safety and quality control.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cp\u003ePart of the modular ABB S800 I\/O system architecture\u003c\/p\u003e\n  \u003cp\u003eSupports RS-422 differential inputs for high-speed pulse counting\u003c\/p\u003e\n  \u003cp\u003eHot-swappable design allows replacement without system downtime\u003c\/p\u003e\n  \u003cp\u003eDiagnostic capabilities for sensor supply monitoring and wire-break detection\u003c\/p\u003e\n  \u003cp\u003eDirect integration with ABB Freelance and 800xA control systems\u003c\/p\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cp\u003eFlow rate measurement and totalization in chemical and oil and gas plants\u003c\/p\u003e\n  \u003cp\u003eRotational speed and velocity monitoring for turbines and conveyors\u003c\/p\u003e\n  \u003cp\u003eIncremental encoder interfacing for precise position tracking\u003c\/p\u003e\n  \u003cp\u003eBatch processing and high-speed counting in discrete automation\u003c\/p\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eABB\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct ID \/ Ordering Number\u003c\/td\u003e\n      \u003ctd\u003e3BSE013228R1\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eDP820\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003ePulse Counter Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003eS800 I\/O\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Type\u003c\/td\u003e\n      \u003ctd\u003eRS-422 Differential Pulse Inputs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignaling Support\u003c\/td\u003e\n      \u003ctd\u003eIncremental Encoder \/ Pulse Train\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMounting\u003c\/td\u003e\n      \u003ctd\u003eS800 I\/O DIN Rail Mounting Base\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eSweden\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions\u003c\/td\u003e\n      \u003ctd\u003e4.3 x 10.5 x 11.8 cm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNet Weight\u003c\/td\u003e\n      \u003ctd\u003e0.16 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003eVerify the part number and ensure the correct S800 I\/O mounting base is installed on the DIN rail.\u003c\/li\u003e\n  \u003cli\u003eDe-energize the cluster power supply before mounting or removing any I\/O module.\u003c\/li\u003e\n  \u003cli\u003eInspect the module and terminal block for any transport damage or bent pins.\u003c\/li\u003e\n  \u003cli\u003eMechanically lock the DP820 module onto its corresponding MTU (ModuleTermination Unit).\u003c\/li\u003e\n  \u003cli\u003eConnect field wiring for RS-422 pulse sources or encoders to the designated terminals.\u003c\/li\u003e\n  \u003cli\u003eRestore power and verify module configuration through the engineering station.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":52668626731371,"sku":"ABB DP820 3BSE013228R1","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/abb-dp820-3bse013228r1-pulse-counter-rs-422-4nlog2l4nob_f489a0c6-b9e0-44b0-a5d2-70d3a9edd833.jpg?v=1765536008","url":"https:\/\/www.plcprotech.com\/products\/abb-dp820-3bse013228r1-s800-i-o-pulse-counter-rs-422","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
