Safety Devices Overload/short circuit in segment circuit Surge voltage Polarity reversal of power supply Reverse voltage Electronic; with four 4-channel drivers Protective circuits of the power terminal; Protection up to 33VDC Protective circuits of the power terminal; It is necessary to protect the power supply. The power supply unit should be able to supply 4- times (400%) the nominal current of the fuse. Integrated reverse voltage protection Electrical Isolation To provide electrical isolation between the logic level and the I/O area it is necessary to supply the bus module and the digital output module using separate power supply units. Interconnection of the 24V power supplies is not allowed. (For detailed information, refer to the user manual.) Common Potentials 24V main power, 24V segment voltage, and GND have the same potential. FE (functional earth ground) is a separate potential area.
