{"product_id":"rs422-rs485-shield-mit-galvanischer-trennung-copy","title":"RS422 \/ RS485 Shield with a galvanic separation","description":"\u003cp\u003eThe RS485 interface is used in many applications in industrial and home automation (e.g. MODBUS), lighting control (DMX), video surveillance (Pelco D) and many more. Also for the Arduino there are already some RS485 extensions. Unfortunately these are mostly not suitable for professional use, because a galvanic isolation between the Arduino and the RS485 bus is missing. This can lead to malfunctions or damage of the Arduino.\u003c\/p\u003e\n\u003cp\u003eOur shield does not have these disadvantages and comes with the following features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRS485 mode (half duplex)\u003c\/li\u003e\n\u003cli\u003eRS422 mode (full duplex)\u003c\/li\u003e\n\u003cli\u003egalvanic isolation between Arduino and connected RS485 bus\u003c\/li\u003e\n\u003cli\u003eTX pin can be freely selected from pins 0-5 via jumper\u003c\/li\u003e\n\u003cli\u003eRX pin can be freely selected from pins 0-5 via jumper\u003c\/li\u003e\n\u003cli\u003eadjustable automatic transmitter switching on in RS485 mode\u003c\/li\u003e\n\u003cli\u003eadjustable control of transmitter activation via pin 6 or 7\u003c\/li\u003e\n\u003cli\u003eswitchable pull-up, pull-down and terminating resistors\u003c\/li\u003e\n\u003cli\u003eRX and TX LEDs to indicate the activity of the UART\u003c\/li\u003e\n\u003cli\u003econnection of the bus via plug-in screw terminal\u003c\/li\u003e\n\u003cli\u003evarious setting options via DIP switches\u003c\/li\u003e\n\u003cli\u003estackable header\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zihatec","offers":[{"title":"1X Shield","offer_id":53142078193931,"sku":"Wendt17","price":34.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1509\/1638\/files\/rs422-rs485-featherwing-mit-galvanischer-trennung-1975991.jpg?v=1780059676","url":"https:\/\/www.az-delivery.uk\/products\/rs422-rs485-shield-mit-galvanischer-trennung-copy","provider":"AZ-Delivery","version":"1.0","type":"link"}
