Electrical configuration of ET 200eco PN

Electrical isolation
The ET 200eco PN electrical configuration features electrical isolation between:
● 1L+ Non-switched supply voltage (electronic/sensor/load supply)
Electrically isolated from PROFINET IO and 2L+ (load voltage supply)
● 2L+: Switched supply voltage (load voltage supply):
Electrically isolated from all other circuit components.
Can be shut down with influencing the 1L+.
● PROFINET IO interface:
Electrically isolated from all other circuit components.
