7. Electrical Interface
Common This section defines electrical specifications for the following 24V digital I/O of the
specifications Control Box.
for all digital I/O
Install the robot according to the electrical specifications which are the same for all three
inputs.
It is possible to power the digital I/O from an internal 24V power supply or from an
external power source by configuring the terminal block called Power. This block
consists of four terminals. The upper two (PWR and GND) are 24V and ground from the
internal 24V supply. The lower two terminals (24V and 0V) in the block are the 24V input
to supply the I/O. The default configuration uses the internal power supply.
Power If more current is needed, connect an external power supply as shown below.
