Product:Honeywell XS821-22 Push-in terminal socket for pluggable AI/AO modules

The Excel 800 Controller Module (XCL8010A) can communicate with a variety of other devices (see Fig. 4), including any combination of up to sixteen Panel Bus I/O Modules and a large number of LONWORKS devices (e.g. room controllers, LONWORKS I/O modules, 3rd-party devices). The Excel 800 Panel Bus I/O Modules communicate via the Panel Bus, while the Excel 800 LONWORKS Bus I/O modules utilize the LONWORKS communication standard and can thus also communicate with other LONWORKS controllers. The pluggable I/O modules consist of a terminal socket and a removable electronic module, allowing the socket to be mounted and wired before the electronic module is installed. All such electronic modules can be swapped out without disrupting the power and bus connections: Simply unplug the “old” and insert the “new” module.
