Features
The SB-293 Satellite Board expands the capabilities of the PXL-250 Tiger Controller. Depending
upon the application, the SB-293 can add 8 general purpose inputs and 4 general purpose outputs, or
it can add Door Switch and Request to Exit inputs and Door Lock and Alarm outputs for a second
door (one reader per door) with 6 additional general purpose inputs and two additional general
purpose outputs. In a networked access control system, the SB-293 increases the number of doors
that can be managed from 128 to a maximum of 256. Refer to Figure 1 on pages 6 and 7 for a basic
diagram of the PXL-250 access control network, including the SB-293 Satellite Board.
