More Information

Overview Manuals Specifications Signal Integration Interface Configuration Product Applications

Features:

  • PT20G architecture: One processor combines technological control and drive-related processing.
  • Mixed-signal paths: Analog, binary, speed and serial functions share the board.
  • Service indication: Watchdog monitoring and the front display expose processor faults.

PT20G hardware brings measurement, command and communication paths into the same real-time application.

The installed plug-in memory and interface selection remain part of the processor configuration, not optional replacement details.

Fault-code indication gives service teams a direct starting point before reset or board exchange.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • ConditionNew Original ready stock
  • Product FamilySIMADYN D

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Mixed-signal processing: Analog, binary and speed-feedback paths participate in the same PT20G control program.
  • Converter timing: The dedicated SITOR path supports applications that depend on synchronized converter firing control.
  • Project continuity: Restoring the original signal map avoids an external I/O redesign during processor replacement.
  • Serial choice: X01 and X02 operation depends on the installed TTY, V.24 or RS-485 interface arrangement.
  • Memory identity: The MS4x plug-in memory carries the operating system and application program used by the processor.
  • Wiring boundary: An interface change is not valid until the project configuration and field wiring are engineered together.
  • Technological control: Executes open-loop and closed-loop tasks within SIMADYN D systems.
  • Drive-related processing: Handles arithmetic and control functions associated with industrial drive applications.
  • Line-commutated converters: Supports engineered converter-control applications using the PT20G SITOR interface.
Description
6DD1606-2AC0 is the Siemens SIMADYN D PT20G processor module for technological open-loop and closed-loop control, arithmetic tasks, drive-related functions and line-commutated converter control.

6DD1606-2AC0 brings analog, binary, speed-sensing and serial signal paths onto one processor board. In an application engineered around PT20G, this integrated structure lets feedback, command and communications data participate in the same real-time control program.

6DD1606-2AC0 also provides watchdog monitoring and front-panel fault-code indication for service diagnosis. Siemens lists the article at end of product lifecycle without a replacement, so the exact order code, rack arrangement, plug-in memory and interface configuration should be preserved during spare-part planning.

Technical notes
The 6DD1606-2AC0 must not be inserted or withdrawn while voltage is present. It occupies two subrack slots and relies on the installed SIMADYN D configuration, plug-in memory and interface arrangement. Before replacement, isolate power and stop if the existing rack, connector map, memory module or SITOR/serial configuration does not match the documented PT20G installation.

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.
What must match before 6DD1606-2AC0 replaces an installed PT20G board?
The complete 6DD1606-2AC0 article number, subrack arrangement, plug-in memory, connector assignments and application documentation must match the installed PT20G configuration. Stop the replacement if any of these identity or configuration points differ.
Can 6DD1606-2AC0 be inserted or removed while the SIMADYN D rack is energized?
No. The Siemens PT20G manual states that 6DD1606-2AC0 must not be inserted or withdrawn under voltage. Isolate the equipment and follow qualified-personnel procedures before handling the board.
How should the serial interface be selected when reinstalling 6DD1606-2AC0?
Match the interface hardware and existing wiring documented for 6DD1606-2AC0. The PT20G supports 20 mA TTY or V.24 through X01 and RS-485 through X02; an unverified interface change can prevent communication.
What should a technician do when the 6DD1606-2AC0 front display flashes a fault code?
Record the displayed code and system context before resetting 6DD1606-2AC0. The PT20G watchdog and monitoring functions use the seven-segment display to signal detected faults, so the code should guide the documented SIMADYN D diagnostic path.
When is the SITOR interface on 6DD1606-2AC0 relevant to a replacement decision?
It is relevant when the installed PT20G application controls a line-commutated converter through X8. Confirm the existing cable, signal assignment and synchronizing-voltage source before approving 6DD1606-2AC0 for that service position.
Does Siemens provide a direct successor for 6DD1606-2AC0?
No. Siemens lists 6DD1606-2AC0 at end of product lifecycle and states that it is cancelled without a replacement product. Use the exact spare or treat modernization as a separately engineered migration.
