Siemens 6DR1901-5 / 6DR1902-5 Process Controllers

Description

Siemens 6DR1901-5 / 6DR1902-5 Process Controllers

Product Dimensions：

The Siemens 6DR1901-5 and 6DR1902-5 are high-quality Plug-in Power Supply Modules designed for the SIPART DR19 series of industrial process controllers. These modules are essential components that convert mains AC power into the stabilized DC voltages required for the controller’s internal electronics and peripheral sensors.

Product Detailed Description

The SIPART DR19 series is a modular range of digital controllers used for complex industrial loops. The 6DR1901-5 (typically 230V AC) and 6DR1902-5 (typically 115V AC) act as the “engine room” of these units. They are designed as slide-in cards that fit into the rear of the controller housing, ensuring a compact and vibration-resistant assembly.

Note: These modules are often referred to as “Power Supply Units” or “Power Packs” within the SIPART spare parts catalog.

Technical Parameters

Product Advantages

• Modular Maintenance: Because these are plug-in modules, they can be replaced quickly in the event of a power surge or failure without needing to replace the entire controller.
• High Stability: Designed to provide “clean” power even in noisy industrial environments, preventing signal jitter in sensitive 4–20 mA loops.
• Galvanic Isolation: Effectively separates the high-voltage mains power from the low-voltage control signals, protecting both the operator and the downstream sensors.
• Rugged Construction: Built to withstand the heat and continuous operation (24/7) common in process industries like steel or chemical manufacturing.

Important Considerations & Precautions

• Voltage Selection: Crucial! Double-check the label before installation. Inserting a 115V (6DR1902-5) module into a 230V line will result in immediate hardware destruction.
• Electrostatic Discharge (ESD): These are bare electronic boards. Always wear an antistatic wrist strap when handling the modules to avoid damaging the CMOS components.
• Power Down: Never plug or unplug these modules while the controller is powered. Ensure the main supply is disconnected before sliding the card in or out.
• Ventilation: Ensure the controller housing vents are not blocked, as these power modules generate a small amount of heat during operation.

Product Applications

These modules are used exclusively within the Siemens SIPART DR19 controllers, which are found in:

• Chemical/Petrochemical: Controlling temperature and pressure loops in reactors.
• Power Plants: Regulating steam valves and water levels in boilers.
• Food & Beverage: Managing pasteurization temperatures and flow rates.
• Water Treatment: Controlling pH levels and chemical dosing pumps.
• Glass & Ceramics: Precision temperature control for industrial kilns and furnaces.
