• Characteristics
– No galvanic isolation.
– Protection against: Short-circuit, overtemperature, and loss of ground.
– Automatic disconnection in case of undervoltage.
• Terminal assignment for the digital outputs:
The following figure shows an example of the terminal assignment for the digital outputs on
connector X111. Connectors X222 and X333 are assigned analogously.
