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 and/or sink line.
The inputs are accessed through direct connection to the XIO connector (see the previous
table), or through the optional XIO Termination Block. See the documentation supplied with
the termination block for details.
XIO Output Signals
The eight digital outputs share a common, high side (sourcing) driver integrated circuit. The
driver is designed to supply any kind of load with one side connected to ground. It is designed
for a range of user-provided voltages from 10 to 24 VDC and each channel is capable of
switching up to 0.7 A of current. This driver has overtemperature protection, shorted load pro-
tection, and is current limiting. If there is an output short or other overcurrent situation, the
affected output of the driver integrated circuit turns OFF and back ON automatically to reduce
the internal temperature. The driver draws power from the primary 24 VDC input to the robot
through a self-resetting polyfuse.
The outputs are accessed through direct connection to the XIO connector. Optionally, use the
XIO Termination Block. See the documentation supplied with the termination block for details.
High Power Indicator Output Assignment
Output 8 can be assigned to indicate the robot's high power state. When high power is
enabled, this output will turn ON. When high power is not enabled, this output will be OFF.
Use Sysmac Studio to make this configuration if needed.
4.3 Connecting the 24 VDC Cable to the Robot
Power requirements for the user-supplied power supply vary depending on the configuration
of the robot and connected devices. OMRON recommends a 24 VDC, 6 A power supply to
allow for startup current draw from connected user devices, such as solenoids and digital I/O
loads.

: Refer to External Connection Specifications on page
145 for more information about 24 VDC power requirements.
24 VDC Power Supply Connector
The cable and accessory box that came with your system contains the 24 VDC power supply
connector and two pins. Use the following figure to determine the pin arrangement.
