Andover Controls TCX 840 Series VAV Controller

Infinity 840 843 845 846 Terminal Control Unit Infinity TCX 840 family of intelligent programmable stand alone controllers offers versatility in Versatile DDC from Simple VAV to Digital Control of package units VAV boxes and other terminal unit applications The TCX 840 TCX 840 TCX 843 TCX 845 and TCX 846 features several combinations of universal inputs an pressure transducer Form A and Tri state outputs and analog outputs for flexible control the TCX 840 model with the I O configuration that meets your specific control needs The basic TCX 840 model provides low cost cooling only VAV control The TCX 843 with three outputs is perfect for VAV applications requiring reheat control The TCX 845 and TCX 846 full featured models With separate outputs for fan and staged heating and cooling control plus analog outputs for economizer control the TCX 845 and TCX 846 provide the perfect for package unit control oxide varistors and optocouplers provide 2500V isolation on each triac based output on all 840 models to ensure noise free operation and in most cases eliminate the need to install in the field The Infinet true peer to peer communications protocol provides the Infinity TCX 840 series with the to instantly communicate with an Infinity network controller such as the CX 9200 as well as the network of Andover Infinet field controllers Up to 254 TCX 840 series controllers can be to one CX series network controller E A T U R E S Package Unit Universal Inputs for Flexible Configurations Peer to Peer Communications Transparent Data Plain English Language Programming A and Tri State Outputs for and Bidirectional Control On Board Pressure Transducer Airflow Measurement Analog Outputs for Precise of Valves and Dampers Built in Varistors for Noise TCX 840 843 845 846 Terminal Control Unit to the Infinity TCX 840 series is handled via the Infinet bus a twisted pair half duplex RS 485 Communication is accomplished with a token passing protocol which provides full transparent data between all Infinity controllers on the network configuration consists of either two or four Universal inputs that accept voltage 0 5 VDC digital on off signals up to 4 Hz or temperature signals The TCX 840 843 and 846 also provide an on board airflow TCX 843 845 and 846 contain 5 Form A triac based outputs for on off or pulsed control of lighting heat and fan Adjacent outputs can also be configured up to two Tri state outputs providing bidirectional control of dampers and The TCX 845 and the TCX 846 also feature two analog outputs each to control devices such as valves dampers The basic TCX 840 model provides two Form A outputs configurable as a single Tri state output for reduced I O such as cooling only VAV control TCX 840 series controller can be configured to meet the exact distributed control requirements of your using Andover Controls powerful Plain EnglishTM programming language Programs are entered into an TCX 840 an SX 8000 workstation the LSX 280 Lap Top Service Tool or network controller The program is then stored in and by the TCX 840 The on board lithium battery keeps programs backed up in the event of a power failure multiple TCX 840s is inherently easy with Plain English A complete copy of one TCX 840 programs be loaded directly into other TCX 840s without changing any point names or programs The SX 8000 workstation this process even easier with its unique drag and drop feature CAPABILITIES dynamic memory of the TCX 840 can be allocated for any combination of Plain English control programs alarming and data logging Our object oriented language with intuitive keywords provides easy and programming In addition Plain English pre defined and customized functions and powerful math reduce programming time particularly
