More Information

Overview Manuals Applications Configuration Communication Monitoring

Features:

  • Combines two current-measuring inputs in a compact controller.
  • Provides one binary input and one binary output for auxiliary logic.
  • Uses the SIPART DR20 K output configuration with a 230 V AC supply.
The 6DR2004-1 order identifies the DR20 K hardware arrangement, not merely the front-panel controller family.

It supports local process-loop operation where indication, adjustment and closed-loop control are required in one instrument.

Check terminal mapping and fitted communication hardware against the removed controller before energizing the replacement.

Availability is confirmed against the complete 6DR2004-1 identity, required condition, quantity and delivery destination at quotation.

  • Regulate a single industrial process loop from a local panel-mounted controller.
  • Retain an installed DR20 control strategy during a like-for-like maintenance project.
  • Interface current-loop measurements with discrete permissive or alarm logic.
  • The ordering code fixes the 230 V AC DR20 K hardware version.
  • Two current inputs are assigned to the controller measurement path.
  • The binary input and output support configured auxiliary logic.
  • Optional PROFIBUS DP communication requires the documented DR20 interface module.
  • Serial RS-232C or RS-485 capability depends on the fitted interface option.
  • Network settings must be recovered from the installed unit or project records.
  • The front panel presents the process value and operating status locally.
  • Configured limits can support alarm or permissive behavior through the binary I/O.
  • Trend and remote observation depend on the connected control-system interface.
Description
6DR2004-1 belongs to the SIPART DR20 compact-controller platform and combines two current analog inputs with one binary input, one binary output and the K control output. The 230 V AC supply identifies this ordering configuration for installed process-control panels. The compact front panel combines the measured value, controller status and operator access in the same panel instrument, which makes the unit practical for brownfield loop-control cabinets.

Operators use the DR20 for closed-loop duties that require local indication, front-panel adjustment and configurable control behavior. Its modular interface concept lets an engineered system add the communication option documented for the installed controller rather than assuming that every unit carries the same interface. Typical duties include temperature, pressure, flow or level regulation where an established analog loop must continue operating without a complete control-system migration.

Before a replacement is fitted, compare the rear connection assignment, supply voltage, input signal ranges, output hardware and any installed interface module. The process parameters and controller configuration should be recorded before the original instrument is removed. After installation, verify display scaling, control direction, alarm limits and the response of every wired output against the recorded baseline before returning the loop to automatic mode.

Technical notes
Preserve the 230 V AC supply and the exact K-output wiring of 6DR2004-1; a DR20 variant with different power or output hardware is not an electrical substitute.

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.
Which hardware code fixes the supply and I/O arrangement of Siemens 6DR2004-1?
The complete 6DR2004-1 code identifies a SIPART DR20 K unit with 230 V AC supply, two current inputs, one binary input and one binary output.
Can the communication option on Siemens 6DR2004-1 be assumed from its front panel?
No. Inspect the installed option hardware and rear connections because the DR20 family supports different interface arrangements.
Where is Siemens 6DR2004-1 typically retained in a process plant?
It is used for compact closed-loop control duties that need local display, operator adjustment and wired process signals.
What availability statement applies when sourcing Siemens 6DR2004-1?
This is a legacy SIPART configuration; Apter Power confirms the exact hardware, condition, quantity and delivery position during quotation.
Which records should accompany a Siemens 6DR2004-1 replacement review?
Provide the rear-terminal schedule, supply marking, installed option cards, parameter backup and photographs of the complete nameplate.
Which manual evidence is needed before pricing Siemens 6DR2004-1?
Use the SIPART DR20 operating and interface documentation, then submit the required controller version, quantity and destination for a matched quotation.
