3.1.2 General Purpose Input Output Module OPCGPIO
OPCGPIO General Purpose I/O Option Module is used for extension of the
number of digital and analog inputs and outputs of the frequency converter.
Contents: OPCGPIO must be fitted into slot B in the frequency converter.
• OPCGPIO option module
• Extended keypad frame

• Terminal cover
Galvanic Isolation in the OPCGPIO
Digital/analog inputs are galvanically isolated from other inputs/outputs on the OPCGPIO and in the control card of the frequency converter. Digital/analog outputs
in the OPCGPIO are galvanically isolated from other inputs/outputs on the OPCGPIO, but not from these on the control card of the frequency converter.
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.
