Electrical isolation
Digital modules
In the digital input/output modules, the grounds of the control voltage (GNDs) and the auxiliary voltage
(GNDp) are connected to each other!
Check this at the documentation of each used EtherCAT Box.
Analog modules
In the analog input/output modules the grounds of the control voltage (GNDs) and the auxiliary voltage
(GNDp) are separated from each other in order to ensure electrical isolation of the analog signals from the
control voltage.
In some of the analog modules the sensors or actuators are supplied by Up - this means, for instance, that in
the case of 0...10 V inputs, any reference voltage (0...30 V) may be connected to Up; this is then available to
the sensors (e.g. smoothed 10 V for measuring potentiometers).
Details of the power supply may be taken from the specific module descriptions.
NOTE
Electrical isolation may be cancelled!
If digital and analog fieldbus boxes are connected directly via four-core power leads, the analog signals in
the fieldbus boxes may be no longer electrically isolated from the control voltage!
