| Application or Compatible Series | SIMADYN D SR24.2 subracks |
Product Overview
The Siemens SIMADYN D SP9 power supply plugs into the SR24.2 rack and supplies the inserted modules through the L and C backplane buses. It includes input and output voltage monitoring, status indicators, reset control, voltage test sockets and backup-battery connections.
It is intended for the 24 V DC-powered SR24.2 configuration and provides monitored rack voltages through the SIMADYN D backplane. Selection and commissioning must account for the specified input range, output rails, fault response and backup-battery connections.
Key Functions
Monitored Rack Power
The unit supplies the 5 V and plus or minus 15 V rails used by modules in the SR24.2 rack.
Defined Fault Response
Input overvoltage, input undervoltage and output undervoltage conditions trigger documented indication and shutdown behavior.
Service and Backup Connections
Front-panel indicators, voltage test sockets, reset control and an external backup-battery connection support maintenance work.

Frequently Asked Questions
Which SIMADYN D rack configuration uses 6DD1683-0BE0?
The SP9 unit is used with the 24 V DC-powered SR24.2 subrack configuration.
What input voltage should be maintained for 6DD1683-0BE0?
The incoming supply must remain within the permitted range of 20 to 30 V DC.
How can a technician reset the rack through 6DD1683-0BE0?
A cold restart can be initiated with the reset button or by jumpering pins 1 and 2 of connector X4.
Can an external backup battery be connected to 6DD1683-0BE0?
An external backup battery can be connected through pins 1 and 2 of connector X3.
What do the status indicators on 6DD1683-0BE0 show?
The green indicator shows fault-free operation, while the red indicator signals a fault condition.
What happens when the 5 V output of 6DD1683-0BE0 falls below its monitored threshold?
The red fault indicator lights, the outputs shut down and the supply requires line voltage to be disconnected before restart.
What cabinet cooling provision is needed when 6DD1683-0BE0 is used in the SR24.2 rack?
Because the SR24.2 configuration has no fan, the cabinet must provide suitable cooling-air slots for self-convection.
Compatibility & Ordering Notes
Compatibility Checklist for 6DD1683-0BE0
- Match SIMADYN D SP9 Power Supply Unit and the full article number character by character.
- Verify maximum input current for sr24: 32 A at maximum rack insertion.
- Confirm main output current for sr24: 0 to 52 A.
- Preserve the approved settings and connection records used in SIMADYN D SR24.2 subracks.
