Control Card, Rs485 Serial Communication; Control Card, Usb Serial Communication; Relay Outputs - Danfoss VLT AutomationDrive EZ FC 321 Installation Manual

VLT®AutomationDrive EZ FC 321
Installation Guide
Resolution of analog output
The analog output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
5.3.7 Control Card, 24 V DC Output
Terminal number
Output voltage
Maximum load
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same potential as the analog and digital
inputs and outputs.
5.3.8 Control Card, +10 V DC Output
Terminal number
Output voltage
Maximum load
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.

5.3.9 Control Card, RS485 Serial Communication

Terminal number
Terminal number 61
The RS485 serial communication circuit is galvanically isolated from the supply voltage (PELV).

5.3.10 Control Card, USB Serial Communication

USB standard
USB plug
Connection to the PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB ground connection is not galvanically isolated from protective earth. Use only an isolated laptop as PC connection to the
USB connector on the drive.
