AF-650 GP and AF-600 FP OPCGPIO General Purpose I/O Option Module
1.2.1 Galvanic Isolation in the OPCGPIO
1
Digital/analog inputs are galvanically isolated from other inputs/outputs on the OPCGPIO and in the control card of the frequency converter. Digital/analogue
outputs in the OPCGPIO are galvanically isolated from other inputs/outputs on the OPCGPIO, but not from these on the control card of the drive.
If the digital inputs 7, 8 or 9 are to be switched by use of the internal 24 V power supply (terminal 9) the connection between terminal 1 and 5 which is illustrated
in the drawing has to be established.
