11.4 Option
11-86
[11] Analog interface card (OPC-G1-AIO)
The analog interface card has the terminals listed below. Mounting this interface card on the
FRENIC-MEGA enables analog input and analog output to/from the inverter.
• One analog voltage input point (0 to ±10 V)
• One analog current input point (4 to 20 mA)
• One analog voltage output point (0 to ±10 V)
• One analog current output point (4 to 20 mA)
Ports available for the communications card
This interface card can be connected to any one of the three option connection ports (A-, B-, and C-ports)
on the FRENIC-MEGA.
Applicable ROM version
This interface card is applicable to inverters with a ROM version G1S10700 or later.
