{"product_id":"m5stack-isolated-rs485-unit","title":"M5Stack Isolated RS485 Unit","description":"\u003cp\u003eThis RS485 Unit is an isolated half duplex transceiver based on the RS485 bus protocol. It can convert TTL level to RS485 level. Since various electrical noises and transient changes of voltage and current may affect communication, using CA-IS3082W as an interface chip can effectively shield the above noise and provide sufficient protection for expensive control equipment and reduce the risk of damage.\u003c\/p\u003e\n\u003cp\u003eCommunication with RS485 devices requiring long-distance signal transmission is possible. The product has a failure protection function whereby in the receiving state, if the input is open or short circuited, the receiver output level is high.\u003c\/p\u003e\n\u003cp\u003eRS485 is a communication protocol standard, which is used to define the electrical characteristics of drivers and receivers used in serial communication systems. It supports Multipoint Systems and is widely used in industrial fields.\u003c\/p\u003e\n\u003cp\u003eWhen the project equipment needs communication control through RS485 and has high requirements for signal-to-noise ratio and transmission distance, it is a good choice to use ISO485 unit for interface type transfers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: The unit no longer ships in a plastic box.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2 id=\"product-features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt in CA-IS3082W isolation chip\u003c\/li\u003e\n\u003cli\u003eIndicator light\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\u003eUp to 1000 VRMs isolation and withstand voltage\u003c\/li\u003e\n\u003cli\u003eDevelopment platform: Arduino, UIflow (Blockly, Python)\u003c\/li\u003e\n\u003cli\u003e2X LEGO™ compatible holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"include\"\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Isolated RS485 Unit\u003c\/li\u003e\n\u003cli\u003e1x VH-3.96 4P\u003c\/li\u003e\n\u003cli\u003e1x 120Ω resistance\u003c\/li\u003e\n\u003cli\u003e1x Grove Cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003ch2 id=\"specification\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eResources\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 value\u003c\/td\u003e\n\u003ctd\u003e1000V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum number of nodes\u003c\/td\u003e\n\u003ctd\u003e256个\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 function\u003c\/td\u003e\n\u003ctd\u003eFailure protection, over-current protection and thermal shutdown protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNew Weight\u003c\/td\u003e\n\u003ctd\u003e13g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e25g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e56mm x 24mm x 11mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e70mm x 55mm x 13mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cli\u003eDocuments\u003c\/li\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":48624222044378,"sku":"jzm1789687051984","price":8.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/m5stack-isolated-rs485-unit_1.jpg?v=1789687057","url":"https:\/\/memoryfoamwear.shop\/products\/m5stack-isolated-rs485-unit","provider":"My Store","version":"1.0","type":"link"}
