The supply voltage can be connected redundantly. Both inputs are
uncoupled. With redundant supply, the transformer supplies the device
alone with the higher output voltage. The supply voltage is electrically
isolated from the housing.
You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24V and 0V pins to connect the AC voltage
