I/O Wiring Details Digital Inputs/Outputs
Digital Inputs
1) You can set the input contact to contact A (normally open) or contact B (normally closed).
2) You can assign each input contact to one of 31 functions.
3) For more information on signal assignment and change of the input contact, refer to the User
Manual, section 10.2 “Input/Output Signals Setting.” The Drive CM software makes setting the
I/O signals very quick and easy.
4) The rated voltage is 12VDC to 24VDC.

Digital Outputs
1) You can set the output to contact A (normally open) or Contact B (normally closed).
2) You can assign each output contact to one of 19 output functions.
3) For more information on signal assignment and change of the output contact, refer to the User
Manual, section 10.2 “Input/Output Signals Setting.” The Drive CM software makes setting the
I/O signals very quick and easy.
4) Excessive voltage or overcurrent may damage the device because it uses an internal transistor
switch. Be cautious.
5) The rated voltage and current are 24VDC

NOTE 1: DO1 and DO2 outputs use separated GND24 terminals, and DO3–DO8 outputs use a
common GND24 for DOCOM.
NOTE 2: DO6–DO8 outputs are locked for alarm group outputs. You can assign desired output
signals to DO1–DO5 for use.
