Block schematics
In the DSC2P rack formats, all parts are on a single board: the servo board.
They need to be powered by an external power supply. The power supply developed by ETEL (refer to the
'DSO-PWS User's Manual'
for more information) is designed to fit most applications. If you use another power
supply, it must meet all the specifications written on the next page.
On the servo board, the power part and the control part are galvanically separated. The inputs and outputs are
insulated from the control part by opto-couplers.
Caution:
The GND is internally connected to the DSC2P front panel which is connected to the
ground (PE).
The power GND is not connected to the ground (PE).
