Product Description
. . . . . 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. Each T-Line module is associated with a single T-Line Graphic Function Block (GFB) downloaded into the TNI module. Sample T-Line GFBs are available from the BBS which can be used as a starting point for customizing the GFBs for your specific application. However, before customized FBs can be downloaded, they must be made in Eikon according to the Zone GFBs standards. The small percentage of Zone GFBs which can not be made in Eikon can be reviewed and encrypted by Dealer Services. NOTE: To operate this module based on a schedule, it must be networked with a Gateway module. Figure 1: T540 Top and Side View Dimensions Specifications: Power: 24 VAC ±10%, 50-60 Hz, 2.4 VA (0.10A) maximum. Inputs: T320/T320v - (2) Dry contact or thermistor. T540/T540v - (4) Dry contact or thermistor, two of which can be configured as 0-5 VDC. Custom translation tables allow nonstandard signals. If used, the RSZ+ requires 2 inputs. Outputs: (T320,T320v = 3; T540, T540v = 5): Digital outputs, rated 1 Amp @ 24 VAC. See Figure 2 for allowable configuration. Flow Sensor: (T320v, T540v only) Range of 0-2" w.c., 0.003" wc resolution. Status Indicator: LED indicators for visual status of receive, transmit/run, and each output. Communications: EIA-485 port for communicating on the Tnet. Memory (T-Line): Non-volatile storage of default control algorithm. Memory (TNI): 128k bytes of non-volatile storage divided into 8 banks of 16k per module (virtual and real). Protection: Bussed output relays to eliminate phasing problems, surge protection on network lines and on input power, arc suppression on relays. (Use the Optional T-net Protection Board (TNPB) which is available for additional network surge protection.). Automated Logic. Automated Logic Corporation. T320.
