    INTRODUCTION Description of Devices The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone Manager and Excel 10 controllers over the Echelon tool. The W7761A device uses Echelon transceiver (FTT) for greater network installation flexibility. The Excel 10 RIO device can be combined with the Excel 10 Zone Manager (FTT), other Excel Controllers, and the Excel Building Supervisor, to provide a complete and low cost control solution for small to large commercial buildings.

    Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the controllers to use their physical inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU Controller.

  • Page 18: Step 2. Determine Other Bus Devices Required

    Step 2. Determine Other Bus Devices Required A maximum of 62 nodes can communicate on a single E-Bus segment. Each W7761A (RIO), W7750 (CVAHU), W7751 (VAV) Controller or T7780 Wall Module constitutes one node. If more nodes are required, a Q7751A Router is necessary. Using a router allows up to 125 nodes, divided between two E-Bus segments.

For wall module wiring, US part AK3782 (non-plenum) or US part AK3792 (plenum) can be used. These cables contain two twisted pairs (one for the run down to the wall module, and one for the run back up to the controller) for ease of installation.
