It can convert TTL level to RS485 level. In the communication link of devices, various electrical noises and transient changes in voltage and current may occur. Using the CA-IS3082W as the interface chip can effectively shield these noises and transients, providing full protection for expensive control equipment and reducing the risk of damage. It communicates with RS485 devices on the other end, making it suitable for long-distance signal transmission. This product features fail-safe protection; in the receiving state, if the input is open or shorted, the receiver outputs a high level. RS485 is a communication protocol standard that defines the electrical characteristics of drivers and receivers for serial communication systems, supporting multi-point systems and used in industrial fields. When project equipment requires RS485 communication control and has high requirements for signal-to-noise ratio and transmission distance, using \u003cstrong\u003eUnit RS485-ISO\u003c\/strong\u003e for interface type conversion is a good choice.\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in CA-IS3082W isolation chip\u003c\/li\u003e\n\u003cli\u003eIsolated DC-DC\u003c\/li\u003e\n\u003cli\u003eSignal transmission rate: Up to 500 Kbps\u003c\/li\u003e\n\u003cli\u003eFail-safe receiver (bus open, short circuit)\u003c\/li\u003e\n\u003cli\u003eSupports up to 256 bus nodes\u003c\/li\u003e\n\u003cli\u003eIsolation withstand voltage up to 1000 VRMS\u003c\/li\u003e\n\u003cli\u003eDevelopment platforms: Arduino, UIFlow (Blockly, Python)\u003c\/li\u003e\n\u003cli\u003e2 x LEGO compatible holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit RS485-ISO\u003c\/li\u003e\n\u003cli\u003e1 x VH-3.96 4p\u003c\/li\u003e\n\u003cli\u003e1 x 120Ω resistor\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove cable (20cm)\u003c\/li\u003e\n\u003cli\u003e1 x I\/O Sticker\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCommunication between RS485 interface devices and microcontrollers in industrial equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWithstand Voltage\u003c\/td\u003e\n\u003ctd\u003e1000V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Nodes\u003c\/td\u003e\n\u003ctd\u003e256\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD\u003c\/td\u003e\n\u003ctd\u003e±15KV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Features\u003c\/td\u003e\n\u003ctd\u003eFail-safe, Overcurrent protection, Thermal shutdown protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e56.0 x 24.0 x 10.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e9.1g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e138.0 x 93.0 x 11.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e17.8g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":53774128972141,"sku":"tgd1787247098819","price":6.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0526\/9869\/files\/isolated-rs485-unit_1.jpg?v=1787247104","url":"https:\/\/www.ruralgoods.shop\/products\/isolated-rs485-unit","provider":"My Store","version":"1.0","type":"link"}
