{"product_id":"pl4-dev-09526","title":"KTA-223 USB\/RS485 Relay IO Board","description":"\u003cp\u003eThe KTA-223 Relay Board is a USB or RS485 controlled module that can interface a PC to eight or more SPDT relays. This could be very useful for controlling real world devices - such as lights and sprinkler systems - and reading sensors or monitoring switches and other digital signals.\u003c\/p\u003e  \n\n \u003cp\u003eThe controller is based on the hardware of the extremely popular Arduino platform. It can be programmed as a stand-alone controller using the free, open source Arduino environment. Internally, the controller is œshield-compatible, allowing the use of many extension boards designed for the Arduino Deumilanove.\u003c\/p\u003e  \n\n \u003cp\u003eThe on-board relays are capable of switching up to 5A at 250VAC, 10A at 120VAC and 10A at 24VDC, but the PCB traces can only handle up to about 5A.\u003c\/p\u003e  \n\n \u003cp\u003eWith the default firmware, a simple ASCII protocol allows control from Windows\/Mac\/Linux using either USB Virtual COM drivers or RS485. Additionally, multiple devices can be connected to one RS485 bus, allowing control of many devices from one USB port.\u003c\/p\u003e  \n\n \u003cp\u003eA large number of mating screw terminals are included with this product. USB cable not included.\u003c\/p\u003e\n\n\u003cp\u003e**Note:** To get this to work with the R3 version of the Arduino Ethernet shield you will need to connect Pin 1 of the ICSP header to D12, Pin 3 to D13 and Pin4 to D11.\u003c\/p\u003e\n\n\u003cp\u003e**Features:**\u003c\/p\u003e\n\n\u003cp\u003e* 8 Relay Outputs 5A 250VAC\u003cbr\u003e\n* 4 Opto-Isolated Inputs 5-30VDC\u003cbr\u003e\n* 3 Analog Inputs (10 bit)\u003cbr\u003e\n* Connections via Pluggable Screw Terminals\u003cbr\u003e\n* 0-5V or 0-20mA Analog Inputs, Jumper Selectable\u003cbr\u003e\n* 5A Relay Switching\u003cbr\u003e\n* Power Indicator LED\u003cbr\u003e\n* All enclosed in Professional looking plastic case\u003cbr\u003e\n* Arduino Compatible\u003cbr\u003e\n* Accepts Arduino Shields (Ethernet \/ XBee)\u003cbr\u003e\n* USB Virtual COM or RS485 Input\u003cbr\u003e\n* Easily connect multiple units far apart by RS485\u003cbr\u003e\n* Updated firmware - fixes a bug with the Relay Status command (status of wrong relay was reported)\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [User's Manual](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/KTA-223-Manual.pdf)\u003cbr\u003e\n* [Schematic](https:\/\/cdn.sparkfun.com\/datasheets\/Dev\/Arduino\/Other\/KTA-223v12.pdf)\u003cbr\u003e\n* [Product Page](http:\/\/www.oceancontrols.com.au\/KTB-223.html)\u003cbr\u003e\n* [VB2k8 Test Software and Source](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/KTA-223-Test-Software.zip)\u003cbr\u003e\n* [VB6 Test Software and Source](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/KTA-223-Tester-VB6.zip)\u003cbr\u003e\n* [Delphi Light Flasher Software and Source](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/KTA-223-delphi.zip)\u003cbr\u003e\n* [Example Arduino ASCII Slave Sketch](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/KTA-223OCRelayDuinoASCIISlaveSKETCH.zip)\u003cbr\u003e\n* [Example I2C firmware](http:\/\/www.sparkfun.com\/datasheets\/DevTools\/Arduino\/Softi2cMaster.zip) - allows the use of a [RTC module](http:\/\/www.sparkfun.com\/commerce\/product_info.php?products_id=99) with the relay unit\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39690068689077,"sku":"PL4-DEV-09526","price":246.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/09526-01.jpg?v=1618121280","url":"https:\/\/getcahits.com\/es\/products\/pl4-dev-09526","provider":"PuriLite","version":"1.0","type":"link"}
