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.
① Infeed of supply voltage
② Loop-through of supply voltage
