Andover Controls i2 850 Terminal Controller

I N F I N E T I I 850 Series of Terminal Controllers Infinet II i2 850 851 and 853 controllers provide cost effective DDC of individual terminal units VAV boxes fan powered induction unit ventilators heat pumps etc The i2850 series is a perfect fit for VAV applications where external damper actuators are used And all i2850s feature a built in expansion port for additional I O controllers are perfect for your more demanding control Compact Terminal Controllers VAV Control for a Range of Applications the the i2850 series controller with the input configuration that your application Compatible with Both and Infinity Expandable I O Meets Point Count Needs Universal Inputs with Form A Form K Outputs for Control Options Non Volatile Flash Memory Utmost Reliability Both Application and Operating Flash Memory Allows Easy Software Updates On Board Airflow Sensor Optional Display Keypad Easy Operator Mounted View and Modify Information Optional Andover Sensor Display Local On Board Service Port The i2850 has four full range Universal inputs plus a fifth input for on board air flow sensor for VAV airflow measurement The i2851 contains four Universal inputs as well but does not the on board air flow sensor and is perfect for applications requiring airflow measurement such as heat pumps and fan The i2853 is for dual duct VAV applications It contains two on airflow sensors and four universal inputs three models feature an additional room sensor input which supports Smart Sensor or any standard room temperature sensor plus Form A relays and one Form K Tri state relay output to all i2 controllers the i2850 series features Flash memory user memory and a fast 32 bit processor for faster scan with plenty of additional memory available for data logging of your data i2850 series communicates with the entire Andover Controls Infinet field bus i e both Infinet and Infinet II controllers and is with both the Continuum CyberStation and Infinity SX 8000 Up to 254 Infinet devices can be networked to any Andover controller RELIABILITY WITH FLASH MEMORY i2850 non volatile Flash memory stores your operating system and programs so that in the event of a power loss your BUILDING SMART will be restored when power is In additon the Flash memory allows for upgrades of your operating system via downloads eliminating the need to swap proms The i2850 controllers include an on battery to safeguard your runtime data all point data and log data from being if power is removed input configuration on the i2850 series of four full range Universal inputs that voltage 0 5VDC digital on off counter up to 4Hz or temperature signals The features one on board air flow sensor the provides two All models offer an additional to support the Andover Smart Sensor or any room temperature sensor i2850 series contains three Form A relay and one Form K Tri state output Each relay rated for 24 VAC VDC 3 amp These outputs be used separately for on off or pulsed control lighting heat and fan units The pre configured K Tri state output can be used for bi control of dampers and valves Any two consecutive Form A outputs can configured to form an additional Form K output EXPANSION i2850 series contains an I O expansion port for addition of up to two xP expansion modules on the bottom of the controller The i2 of modules includes the DI 8 D0 2 D0 4 and AO 4 In addition the I O bus supports xP Display Module which allows the user to and change point values CAPABILITIES dynamic memory of the i2850 series can be for any combination of programs alarming and data logging
