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 common source / sink line.

 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.
