Voltage supply

External voltage supply

 Note!

With external voltage supply of the communication module, the active bus

terminating resistor is fed independently of the operation of the basic device.

Thus the bus system remains active even if the basic device is switched off or

fails.

If required, feed the communication module with a separate supply voltage via the

two−pole plug connector.

Use a separate supply unit in every control cabinet if the distance between the control

cabinets is larger than normal.

Plug connector Explanation

"+" V = 24VDC (21.6 V − 0% ... 26.4 V + 0 %)

I = 120 mA

"−" Reference potential for external voltage supply

Controller External voltage supply

820X Always required.

821X / 822X / 824X /

93XX / 9300 servo

PLC / Drive PLC / ECS

servo system

Only necessary, if the mains which supplies the corresponding controllers is

to be switched off but the communication must not be interrupted.

You can use the internal power supply for these controllers.
