Redundant power supplies can be used. Both inputs are uncoupled.
There is no distributed load. With redundant supply, the power supply unit
supplies the device only with the higher output voltage. The supply
voltage is electrically isolated from the housing.
See “Insulation voltage” in section
.
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
