Product Description
. . . . . The XT-9100 Extension Module and XP-910x Expansion Modules have been designed to provide additional input and output capacity within Metasys Networks, specifically for the DX-9100 Extended Digital Plant Controller. The XT-9100 module provides the communications interface, and the XP modules provide the analog and digital inputs and outputs. A Supervisory System communicates with the XT-9100 via the N2 Bus or Bus 91*. See Figure 2. Each XT-9100 can have up to 16 inputs/outputs, eight of which may be analog. The DX-9100 communicates with the XT-9100 via the XT-Bus. When the DX-9100 is connected to the N2 Bus (or Bus 91), data from the XT-9100 is available to a Supervisory System. See Figure 3. Up to eight XT-9100 modules can be connected to the XT-Bus. Each XT provides, depending on the type of the connected XP expansion modules, eight analog or eight digital points, extending the input/output of a DX-9100 by up to 64 remote input/outputs. Modules with 16 input/outputs may also be connected, provided that the total number of remote input/output points on the DX-9100 does not exceed 64.. Johnson Controls. Johnson Controls. XP-9102-8204.
