AC30 series General Purpose I/O Option 
Digital Inputs and Outputs (7004-01-00 only) 
The GPIO option 7004-01-00 offers four identical ports on X20 that can 
be individually configured as digital input or digital output. 
 
Digital Input / Output 11 
(default = unassigned input). 
See the notes below. 
Digital Input / Output 12 
(default = unassigned input). 
See the notes below. 
Digital Input / Output 13 
(default = unassigned input). 
See the notes below. 
Digital Input / Output 14 
(default = unassigned input). 
See the notes below. 
24V DC Input. Required to 
power digital outputs 
DOUT11 to DOUT14. See 
the notes below. 
0V reference for 7004-01-
XXX Digital Inputs and 
Outputs. See the notes 
below. 
 
Note 1: 
If any of X20/01 to X20/04 is to be configured as digital output, then 
X20/05 must be connected to the positive output from a 24V supply, 
and X20/06 must be connected to the negative output from the same 
supply. See the example applications on page 11. 
 
Note 2: 
Digital input and output ports on the 7004-01-00 are fully isolated 
from the drive electronics. Therefore it is essential that X20/06 is 
connected to the user’s 0V signal reference which should be 
grounded at an appropriate point in the system.
