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.

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.

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.
