General Specifications
Analog Output
Number of programmable analog outputs
Terminal number
Current range at analog output
Max. load to common at analog output
Accuracy on analog output
Resolution on analog output
The analog output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals
Control Card, 24 V DC Output
Terminal number
Max. 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.
Control Card, 10 V DC Output
Terminal number
Output voltage
Max. load
8 8
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals
Control Card, RS-485 Serial Communication
Terminal number
Terminal number 61
The RS-485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from
the supplier voltage (PELV).
Control Card, USB Serial Communication
USB standard
USB plug
Connection to 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 protection ground. Use only isolated laptop as PC connection to the
USB connector on the frequency converter drive
Relay Outputs
