4.5 Using Digital I/O on eMB-40/60R XIO Connector
Optional I/O Products
These optional products are also available for use with digital I/O:
l
XIO Breakout Cable, 5 meters long, with flying leads on user’s end. See XIO Breakout
Cable on page 52 for information. This cable is not compatible with the XIO Ter-
mination Block mentioned below.
l
XIO Termination Block, with terminals for user wiring, plus input and output status
LEDs. Connects to the XIO connector with 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 eMB-40/60R 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 the following
table), 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 trig-
gers. Refer to the eV+ user guides on the corporate website.
