EXCEL 10 W7761A INPUT/OUTPUT DEVICE

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® LonWorks® E-Bus. These I/O points are configured with the E-Vision

tool. The W7761A device uses Echelon® LonWorks® communication technology and a new free topology twisted pair 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.

The Q7750A Excel 10 Zone Manager is a communications interface that allows devices on the E-Bus network to communicate with devices on the standard EXCEL 5000® System C-Bus. Fig. 1 shows an overview of a typical system layout. The Q7750A also provides some control and monitoring functions.
