TIO Internal Circuits
Use the following diagram to understand the TIO internal circuits.
TIO Input Signals
The 5 input channels are optically isolated and share a 24 VDC common.

TIO Output Signals
The 4 outputs share a common, sourcing driver integrated circuit. The driver is designed to supply
a load with one side connected to ground. Each channel is capable of switching up to 0.7 A of cur-
rent. This driver has over-temperature protection, shorted load protection, and is current limiting.
The driver draws power from the primary 24 VDC input to the robot through a self-resetting poly-
fuse.
Precautions for Correct Use
Use surge suppression when switching inductive loads such as relays to prevent damage to the
output circuits.
Additional Information
If there is an output short or other over-current condition, the affected output of the driver inte-
grated circuit turns OFF until the condition is removed.
