Automated Logic T540 T-Line Zone Control Module [] in Tempe, AZ, USA

. . . . . The T-Line is part of the I/O Hardware family of control modules and is designed specifically for zone control. The T-Line consists of the T320, T320v, T540, and T540v ("v" indicates the board has a flow sensor). A single main board provides the power circuitry, the microprocessor, and nonvolatile memory. The name of the module indicates the number of outputs and inputs which it provides. The T-Line modules are designed to be mounted directly on the equipment being controlled, such as VAV boxes, heat pumps, unit ventilators, and fan coil units. Each T-Line module communicates with the CMnet through a Tnet Interface module (TNI) (see Figure 6). Each T-Line module can store an optional default algorithm (see T-Line Default Algorithm Downloader TI for more information) which maintains the space temperature in the event that communications is lost with the TNI module.
