Inputs & Outputs
11.3.2 Internal I/O Connections (Conn. option 34X)
The Internal I/O Connection option consists of taking
the ribbon cable from the back of the I/O board to a
board in the back of the controller. This board breaks
out the ribbon cable to individual terminals. The I/O that
is run through this board is 24 VDC or less. This same
board is used for wiring of analog signals.
Example: Digital Input
If establishing a digital input, a limit switch is to be wired
to input number 6 on an I/O board. The limit switch must
have 24 VDC supplied to one side of the limit switch.
(Possibly from XS3/XT3 terminals A15-A16 or B15-
B16 or C16) The other side of the limit switch would be
wired to XTXX terminal 7. For the input to work, 0 VDC
(of the source voltage) would have to be connected to
XTXX terminal 10. If inputs 9 - 16 are to be used, 0 VDC
must also be connected to terminal 20.
Example: Digital Output
If a light is to be wired to output 12 on an I/O board, it
would have 0 VDC connected to one side, and the other
would be wired to XTXX terminal 35. For the output to
work, 24 VDC and 0 VDC must be supplied to this group
of outputs. This can be done by wiring 24 VDC from
XS3/XT3 to XTXX terminal 31, and 0 VDC on the XSXX
terminal 40.
Example: Analog Input
For the analog inputs to work, a source voltage (+/- 15
VDC) must be applied to the board. This voltage can be
supplied from a customer source or from a robot
source. (Robot sources at XT10 pins 35, 36, 37, 38, 39,
and 40) If an analog input, such as a pressure device,
is to be wired to analog input 1, one side of the device
would be fed the source voltage, and the other connected
to the XT10 terminal 2. For the input to work, 0 VDC
must be connected to XT10 terminal 5.
Example: Analog Output
For the analog outputs to work, a source voltage (+/- 15
VDC) must be applied to the board. This voltage can be
supplied from a customer source or from a robot
source. (Robot sourced at XT10 terminals 35, 36, 37,
38, 39 and 40). If an analog output, such as a flow
control device, is to be wired to analog output 3, one
side of the flow control device would be wired to XT10
terminal 10, and the other wired to 0 VDC. The output
would also need XT10 terminal 11 connected to 0VDC.
