All the I/O must comply with the specifications. The digital I/O can be
powered by a internal 24V power supply or by an external power supply
by configuring the power junction box. In the following figure, PWR is
the internal 24V power output. The lower terminal (24V-IN) is the 24V
input external power input for I/O. The default configuration is to use
internal power, see below.
If larger current is needed, connect the external power supply as shown
below.
The electrical specifications for the internal and external power supplies
are as follows.
