(excl. supply of ModuleBus and CEX-Bus. For details,
refer to
3BSE036351R, AC 800M - Controller Hardware,
Hardware and Operation
).
Power Input Connector Four pin, screw connector L+, L–, SA and SB.
Power Supply
Requirements
Inputs designated L+ and L– 24 V nominal, variation
between 19.2 V DC and 30 V DC.
Redundant Power
Supply Status Inputs
Inputs designated SA, SB
• Max input voltage 30 V
• Min. input voltage for high level 15 V
• Max input voltage for low level 8 V
These inputs are status inputs. The threshold levels are
logical "0" or "1" input limits, not power fail limits.
Power Reservoir The processor unit has an internal 5ms power reservoir,
sufficient for the CPU to make a
controlled power down.
Protection Rating IP20 according to EN60529, IEC 529.
