provides Infinity TCX 850 with the ability to instantly communicate with an Infinity network controller such the CX 9200 as well as the entire network of Andover Infinet field controllers Up to 254 TCX 850s be networked with the Infinity CX family of controllers to the Infinity TCX 850 is handled via the Infinet bus a twisted pair half duplex RS 485 interface Communica is accomplished with a token passing protocol which provides full transparent data transfer between all Infinity controllers the network the TCX controller with the input configuration that matches your application The TCX 850 has four full range inputs that accept voltage 0 5VDC digital on off counter signals up to 4 Hz or temperature signals plus a fifth which is an on board air flow sensor Three field adjustable potentiometers provide min max and setpoint adjustments TCX 851 comes without the on board airflow sensor for applications not requiring airflow measurement such as heat and fan coils It contains four Universal inputs but does not contain the three potentiometers TCX 852 contains two Universal inputs and the on board airflow sensor for reduced I O applications It does not contain three potentiometers TCX 853 is for dual duct VAV applications It contains two on board airflow sensors and six Universal inputs It does not the three potentiometers TCX 855 is identical to the TCX 850 with the exception that it contains a lower range 0 0.2 W C airflow sensor to lower air volume applications Stand Alone DDC for System Peer to Peer Communications Transparent Data Plain English Language Programming Universal Inputs for Flexible Configurations A and Tri State Outputs for and Bidirectional Control On Board Pressure Transducer Airflow Measurement Expandable I O Meets Additional Count Needs Battery Backup for Ten Years Power Failure of Memory TCX 850 851 852 853 855 Terminal Control Unit TCX 850 851 853 and 855 contain three Form A relay outputs for on off or pulsed control of lighting heat and fan One Tri State output provides bidirectional control of dampers and valves Optional analog output pneumatic output high voltage output modules are available TCX 852 contains one Form A output and one Tri State output for reduced I O applications EXPANSION TCX 850 851 853 and 855 contain the I O expansion port for the addition of low cost I O modules directly on the of the controller The family of modules includes the EMX 140 2 pneumatic outputs EMX 150 2 analog outputs 155 2 digital outputs and the EMX 160 8 digital inputs The EMX 170 Programmable Interface provides a low cost user interface and temperature sensor It contains an 8 character LCD display and six programmable that enable the user to view temperatures adjust setpoints and switch to occupied mode TCX 850 can be configured to meet the exact distributed control requirements of your application using Andover powerful Plain English programming language Programs can be activated within individual TCX 850s or any controller Programs are entered into an TCX 850 using an SX 8000 workstation the LSX 280 Lap Top Service Tool network controller The program is then stored in and executed by the TCX 850 The on board lithium battery keeps backed up in the event of a power failure multiple TCX 850s is inherently easy with Plain English A complete copy of one TCX 850 programs can be directly into other TCX 850s without changing any point names or programs The SX 8000 workstation makes this even easier with its unique drag and copy feature CAPABILITIES dynamic memory of the TCX 850 can be allocated for any combination of Plain English control programs scheduling and data logging Our object oriented language with intuitive keywords provides easy operation and program In addition Plain English pre
