Description

Siemens 6DR1901-5/6DR1902-5 Intelligent Electric Valve Positioner

Product Dimensions：

The Siemens SIPART DR19 (specifically the 6DR1901-5 and 6DR1902-5 series) is a high-performance digital industrial controller designed for complex technological tasks. It is widely recognized for its reliability in controlling temperature, pressure, flow, and level in various industrial processes.

Product Specifications & Parameters

The 6DR190x-5 series belongs to the SIPART DR19 family, featuring a compact $96 \times 48 \text{ mm}$ format.

Key Product Advantages

• Modular Flexibility: The basic unit can be expanded with additional input/output modules (digital inputs, analog outputs, or communication interfaces) to suit specific site requirements.

• Intuitive Operation: Equipped with clear digital displays and green/red LED bargraphs for immediate visual confirmation of the process value and setpoint.

• Built-in Functions: Includes specialized functions like Square Rooting (for flow measurement) and Linearization (for thermocouples/sensors).

• Seamless Integration: Supports standard communication protocols for integration into higher-level SCADA or PLC systems.

• Durability: Built to withstand harsh industrial environments with high electromagnetic compatibility (EMC).

Important Considerations & Maintenance

• Wiring Safety: Ensure the power supply matches the specific model (e.g., do not connect 230V to a 6DR1901-5 unit).

• Heat Dissipation: When installing multiple units in a control cabinet, maintain the recommended spacing to avoid overheating.

• Configuration: The device is programmed via the front keys or through “SIPROM DR” software. Accurate parameterization of the PID values is crucial to prevent process oscillation.

• Signal Interference: Use shielded cables for analog inputs/outputs to prevent electrical noise from affecting the measurement accuracy.

Industrial Applications

The SIPART DR19 is a “workhorse” in sectors requiring precise regulatory control:

1. Chemical & Petrochemical: Controlling reactor temperatures and pressure vessels.

2. Food & Beverage: Managing pasteurization temperatures and sterilization processes.

3. Water Treatment: Maintaining pH levels and flow rate regulation.

4. Furnace Construction: Precise ramp/soak control for industrial ovens and kilns.

5. Power Generation: Auxilliary control loops for cooling water and steam systems.
