More Information

Overview Manuals Input Conversion Dual-Rail Output Operator Controls Fault Handling

Features:

  • 6ES7407-0RA01-0AA0 accepts either a wide-range AC input or a DC input.
  • The supply produces a 5.1 VDC system rail and a separate 24 VDC auxiliary rail.
  • Front controls cover standby, battery monitoring and failure-message reset.
The module feeds S7-400 electronics through the rack while exposing both secondary-voltage states on the front panel.

The three-pin power connector and protective conductor remain on the primary side of the conversion boundary.

Two battery compartments support the selectable backup arrangement monitored by the front BATT indicators.

The Siemens 6ES7407-0RA01-0AA0 S7-400 PS 407 20 A Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

One Connector for AC or DC

  • Shared connector: The same three-pin plug accepts the documented AC or DC supply.
  • AC path: AC operation covers 85–264 V at 47–63 Hz.
  • DC path: DC operation covers 88–300 V and tolerates reversed L+ and L− without loss of function.

System and Auxiliary Supplies

  • System rail: The 5.1 VDC rail is rated for 20 A.
  • Auxiliary rail: The 24 VDC rail is rated for 1 A.
  • Rail indicators: Separate front indicators show the presence of each output.

Standby, Battery and Reset

  • Standby control: The standby switch changes operating state but does not isolate mains power.
  • Battery selection: The battery selector enables one-battery, two-battery or off monitoring.
  • Failure reset: FMR clears stored failure messages after the fault condition is removed.

Shutdown and Restart Sequence

  • Internal fault: INTF separates an internal supply fault from a missing output indication.
  • Backup faults: BAF and the two battery LEDs identify backup-related conditions.
  • Restart cycle: Short circuit or overload initiates a delayed shutdown followed by a restart attempt.
Description
Power for an S7-400 rack is generated by Siemens 6ES7407-0RA01-0AA0, the PS 407 20 A supply module. Its wide-range input accepts either 85–264 V AC or 88–300 V DC and produces the 5.1 VDC system rail together with a 24 VDC auxiliary output.

The front panel of 6ES7407-0RA01-0AA0 separates operating control from fault recognition. A standby switch changes the module state without isolating the mains connection, the battery selector chooses one battery, two batteries or no battery monitoring, and the FMR button resets stored failure indications after the cause has been removed.

Status paths on 6ES7407-0RA01-0AA0 cover internal faults, battery faults and both output rails. During a short circuit or overload, the supply switches off after the defined delay and then attempts a restart, allowing the 5 V and 24 V indicators to show whether the secondary voltages have returned.

The 6ES7407-0RA01-0AA0 module occupies the 75 mm power-supply width in the S7-400 assembly and connects through a three-pin power plug. Its two battery compartments support backup monitoring, while the protective-conductor connection and input category define the primary-side installation boundary.

Technical notes
The standby switch on Siemens 6ES7407-0RA01-0AA0 does not disconnect the mains input. Isolate the primary supply before wiring, and verify both secondary rails after fault reset.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 6ES7407-0RA01-0AA0 be powered from a DC source instead of AC mains?
Yes. 6ES7407-0RA01-0AA0 accepts 88–300 V DC as well as 85–264 V AC through the documented three-pin power connection.
Does the standby switch on 6ES7407-0RA01-0AA0 make the input terminals safe to touch?
No. The standby switch on 6ES7407-0RA01-0AA0 does not disconnect the mains, so the upstream supply must be isolated before wiring work.
What should be checked when the 5 VDC LED is off but the 24 VDC LED remains on for 6ES7407-0RA01-0AA0?
For 6ES7407-0RA01-0AA0, treat the 5.1 V system rail and 24 V auxiliary rail as separate outputs and inspect the load and fault indication for the missing rail.
Why does pressing FMR not restore a tripped 6ES7407-0RA01-0AA0?
FMR only resets stored failure indications on 6ES7407-0RA01-0AA0; an active overload, short circuit or missing input must be removed first.
How do the BATT1F and BATT2F indicators relate to 6ES7407-0RA01-0AA0 battery settings?
6ES7407-0RA01-0AA0 monitors the battery positions selected by the one-battery or two-battery switch setting and reports the corresponding battery fault separately.
What output should be used for the S7-400 system load on 6ES7407-0RA01-0AA0?
The S7-400 system supply from 6ES7407-0RA01-0AA0 is the 5.1 VDC/20 A rail; the 24 VDC output is a separate 1 A auxiliary path.
