Analog interface card (OPC-AIO)

The analog interface card has the terminals listed below. Mounting this interface card on the
FRENIC-HVAC 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 or 0 to 20 mA, switchable)
- One analog voltage output point (0 to ±10 V)
- One analog current output point (4 to 20 mA)
Ports available for the interface card
This interface card can be connected to any one of the three option connection ports (A-, B-, and
C-ports) on the FRENIC-HVAC.
