The SIPART DR21 is a versatile, compact, and user-friendly single-loop process controller designed for basic control tasks in industrial automation. The specific model 6DR2100-5 N1-VN-06948 is a standard version with a single analog input, relay outputs, and a front panel IP rating of NEMA 4X (IP65), making it suitable for a wide range of applications in various environments.

1. Overall Product Line: SIPART DR21

The SIPART DR21 family is Siemens’ solution for simple control loops where a full-featured, complex system is not required. It is known for its:

• Ease of Use: Simple configuration and operation via a clear front keypad and display.

• Robustness: Designed for harsh industrial environments.

• Flexibility: Available in multiple versions with different input types, outputs, and power supply options.

• Cost-Effectiveness: An economical choice for stand-alone control applications.

2. Decoding the Order Number: 6DR2100-5 N1-VN-06948

Let’s break down the specific product code to understand its exact features:

• 6DR2100: This is the base order number for the SIPART DR21 single-loop controller.

• -5: This suffix typically indicates a specific hardware version or a standard model variant. In this context, it often refers to a common configuration with standard features.

• N1: Front Panel Protection Degree.

  • N1 = IP65 / NEMA 4X. This means the front panel is dust-tight and protected against water jets from any direction. It is suitable for wash-down areas and harsh industrial environments.

• V: Input Type and Control Action.

  • V = One analog input (e.g., 0/4-20 mA, thermocouple, resistance thermometer) with PID control action. The exact sensor type would be specified in the detailed datasheet, but “V” is a common code for a universal analog input.

• N: Output 1 (Main Control Output).

  • N = Relay Output. This is an electromechanical relay suitable for switching AC loads like heaters, solenoid valves, or small motors.

• -06948: This is a specific MLFB (Ordering Code) suffix that defines the complete package. It includes all the options above and locks in the specific configuration. It tells Siemens exactly what to build/ship.

3. Key Features and Specifications (Based on the Code Analysis)

• Control Function: Continuous PID control.

• Input: One universal analog input (likely configurable for voltage, current, or common temperature sensors).

• Outputs:

  • Output 1: One relay output (for the main control action, e.g., heating or cooling).

  • Auxiliary Outputs: The standard DR21 often includes at least one additional alarm or limit value relay output.

• Display: A clear digital display for the process value (PV) and setpoint (SP), typically with indicator LEDs for status (e.g., AUTO/MAN, alarm).

• Front Panel: IP65/NEMA 4X rated, making it suitable for dusty and wet environments.

• Power Supply: Not explicitly stated in this code, but common options are 24V DC, 110V AC, or 230V AC. This would be specified on the device’s nameplate.

• Housing: Compact, designed for mounting in a standard DIN cut-out.

4. Typical Applications

The SIPART DR21 is used wherever simple, reliable temperature, pressure, level, or flow control is needed. Common applications include:

• Industrial Ovens & Furnaces: Temperature control.

• Packaging Machinery: Heat sealing temperature regulation.

• Plastic Processing: Mold temperature control.

• HVAC: Control of heating/cooling units.

• Food & Beverage Industry: Process temperature control in tanks and kettles.

• Water Treatment: Chemical dosing pump control.
