I/O Supply Power

It is possible to power the digital I/O from an internal 24 V 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 24 V and ground from the internal 24 V supply. The lower two terminals (24V and 0V) in the block are the 24 V input to supply the I/O. The default configuration uses the internal power supply.

In this example, the default configuration uses the internal power supply. This is the factory default setting used when the robot is delivered.
