Control card, 24 V DC output
Terminal number
12, 13
Output voltage
24 V +1, -3 V
Maximum load
200 mA
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
±
50
Output voltage
10.5 V
±
0.5 V
Maximum load
15 mA
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
68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61
Common for terminals 68 and 69
The RS-485 serial communication circuit is functionally separated from other central circuits and galvanically isolated from the
supply voltage (PELV).
Control card, USB serial communication
USB standard
1.1 (Full speed)
USB plug
USB type B “device” 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 protective ground. Use only an isolated laptop as PC connection to
the USB connector on the adjustable frequency drive.
