Connecting Flex I/O
Flex I/O describes a number of general purpose inputs and outputs that can be
customized to adopt various functions. The inputs are connected across 0V and one
of the Flex I/O pins (I9, I10, I11, I12).
The example below shows a request to exit switch (RTX) wired to I11. (Flex I/O 3).
The RTX switch is connected to the controller via
the 0V and any of the Flex I/O connectors, I9
(Flex I/O 1), I10 (Flex I/O 2), I11 (Flex I/O 3) or
I12 (Flex I/O 4). The controller will support both
N/O (press to make) and N/C (press to break)
switch types for each Flex I/O input.
The Flex Outputs provide a negative triggered 12Vdc to each of the four Flex Output
terminals (O9, O10, O11, O12).
The illustration on the left shows Flex Output
configured on O9. The connection is 2-wire,
between 12Vdc and O9. O9 providing a switched
0Vdc.
