Digital outputs
• 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.

Terminal assignment for the digital outputs
NOTICE
Damage to the module
If the outputs are overloaded, the heat can melt the contacts.
Therefore, for a demand factor of 100%, a max. current of I
out
= 0.25 A at X111, X222, X333:
Pin 2, must not be exceeded.
