Sedona is an open-source software environment designed to make it easy to build smart, networked, embedded devices, which are well-suited for implementing control applications.\nFreely programmable controller with a modern programming tool, a variety of integration interfaces, and 22 onboard I\/Os is suitable for a wide range of HVAC projects.\n\n\u003cstrong\u003eLocal HMI with a Built-in LCD\u003c\/strong\u003e\nA fully customizable LCD display with a role-based access makes the controller useful in various HVAC scenarios. The ability to treat the LCD as a part of an application makes the operator able to read and set control values, read alarms, set schedules, and configure the controller.\n\n\u003cstrong\u003eData Logging with Instant Access\u003c\/strong\u003e\nThe device is suitable for fast response environments thanks to its instant start-up, real-time clock (RTC), and powerful onboard Cortex-M4 processor. A microSD card slot allows alarms and trend logs to be collected and read in real time.\n\n\u003cstrong\u003eDirect Digital Control\u003c\/strong\u003e\nTo ensure a maximum flexibility of AAC20, it is equipped with 22 I\/Os that can be easily expanded with two RS485 ports using iSMA CONTROLLI multiprotocol I\/O modules.\n\n\u003cstrong\u003e8 Universal Inputs\u003c\/strong\u003e\nSupport for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input.\n\n\u003cstrong\u003e4 Digital Inputs\u003c\/strong\u003e\nDry contact inputs - made for monitoring. 100 Hz fast pulse counter with override function saves the real-time values to the non-volatile memory of the controller.\n\n\u003cstrong\u003e4 Digital Outputs\u003c\/strong\u003e\nDigital outputs equipped with normally open 3 A relays allow for direct control without additional relays.\n\n\u003cstrong\u003e6 Analog Outputs\u003c\/strong\u003e\n0-10 V DC control with 10 mA accuracy, PWM modes, and a maximum load of up to 20 mA to power external relays makes the output suitable for a variety of scenarios (AO5 and AO6 can only be used if 1-Wire port is not in use, maximum current load for AO6 is up to 5 mA)\n\n\u003cstrong\u003eVersatile Integration Platform\u003c\/strong\u003e\nTo make the controller useful in various building scenarios, it is equipped with a variety of open communication protocols over IP and serial buses, like BACnet IP, Modbus TCP\/IP, BACnet MS\/TP, Modbus RTU\/ASCII, M-Bus IP, 1-Wire, or oBIX.\n\n\u003cstrong\u003eSimplified Configuration and Commissioning Process\u003c\/strong\u003e\nConfiguration, programming, and integration are done in one free of charge tool. Two Ethernet ports working in a switch mode allow for daisy chaining of multiple controllers with MIX modules over the RJ45, which enhances the cabling process and reduces the engineering time. The ability for troubleshooting using a built-in web server or a USB port facilitates the engineering process.\n\n\u003cstrong\u003eQuality and Reliability Confirmed by Certificates\u003c\/strong\u003e\niSMA CONTROLLI is a long-standing member of the BACnet community. The experience in developing high-quality products and the BTL (BACnet Test Laboratory) certification confirm the excellent performance of communication using the BACnet protocol.\n\u003ch3\u003eTechnical Specification\u003c\/h3\u003e\n\u003cstrong\u003eHardware Specification\u003c\/strong\u003e\nARM Cortex-M4 dual core CPU\nBuilt-in real-time clock (RTC)\n2 RS485 interface\n2 Ethernet interface with built-in switch\nUSB host interface\n1-Wire interface\nmicroSD card slot\n22 I\/Os onboard\nBuilt-in LCD\n\n\u003cstrong\u003eInputs\u003c\/strong\u003e\n\u003cstrong\u003e8 Universal Inputs (UI)\u003c\/strong\u003e\nTemperature input: 10K3A1, 10K4A1, Carel 10K, 20K6A1, 2.2K3A1, 3K3A1, 30K6A1, SIE1, TAC1, SAT1, Pt1000, Ni1000 0C, Ni 1000 20C, Ni1000 LG 2\nResistive input 0-1000 kΩ\nVoltage input 0-10 V DC\nCurrent input 0-20 mA\nDry contact input\n\n\u003cstrong\u003e4 Digital Inputs (DI)\u003c\/strong\u003e\nDry contact inputs\nFast pulse counter up to 100 Hz saved in the EEPROM memory\n\n\u003cstrong\u003eOutputs\u003c\/strong\u003e\n\u003cstrong\u003e4 Digital Outputs (DO)\u003c\/strong\u003e\nNO relay output\nResistive load max. 3 A at 230 V AC \/ 30 V DC\nInductive load max. 75 VA at 230 V AC \/ 30 W at 30 V DC\n\n\u003cstrong\u003e6 Analog Outputs (AO)\u003c\/strong\u003e\n0-10 V DC output with maximum load up to 20 mA (AO5 and AO6 can only be used if 1-Wire port is not in use, maximum current load for AO6 is up to 5 mA)\nPWM: 0.01 Hz, 0.1 Hz, 1 Hz, 10 Hz, 100 Hz\n\n\u003cstrong\u003eCommunication\u003c\/strong\u003e\nModbus RTU\/ASCII\nModbus TCP\/IP\nBACnet MS\/TP\nBACnet IP\nM-Bus IP\nSOX protocol\noBIX\n1-Wire\nFree software: Sedona Updater \u0026amp; iSMA Tool\nBuilt-in web server\n\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e\n24 V DC ± 20%\n24 V AC ± 20%","brand":"Engenuity Systems","offers":[{"title":"Default Title","offer_id":50732404441346,"sku":"iSMA1B-03","price":858.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/1839\/2578\/files\/aac20-lcd.jpg?v=1792018107","url":"https:\/\/engenuity.com\/products\/isma-b-aac20-lcd-free-programmable-advanced-application-controller","provider":"Engenuity Systems","version":"1.0","type":"link"}
