Features
Two "+" terminals and two "G" terminals are available. These are jumpered in the connector. 
This loops through the power supply.
This power supply is only required for the digital outputs. 
The option slot of the D4x5 Control Unit also provides the following power supplies:
●
Electronic power supply of the TB30
● Supply of the analog inputs and outputs.
The power supply of the digital outputs and the electronic power supply of the Control Unit are 
isolated.
