Optional I/O Products
These optional products are also available for use with digital I/O:
•
XIO Breakout Cable
, 5 meters long, with flying leads on user’s end. See
for information. This cable is not compatible with the XIO Termination Block.
•
XIO Termination Block
, with terminals for user wiring, plus input and output
status LEDs. Connects to the XIO connector with 1.8 M (6 foot) cable. See the
XIO Termination Block Installation Guide
for details.
XIO Input Signals
The 12 input channels are arranged in two banks of six. Each bank is electrically isolated
from the other bank and is optically isolated from the robot’s ground. The six inputs
within each bank share a common source/sink line.
The inputs are accessed through direct connection to the XIO connector (see
), or through the optional XIO Termination Block. See the documentation supplied
with the Termination Block for details.
The XIO inputs cannot be used for REACTI programming, high-speed interrupts, or
vision triggers. See the
for information on digital I/O
programming.
