Description

Siemens RWR462.10 Building Control Module

Product Dimensions：

The Siemens RWR462.10 is a specialized electronic Universal Controller from the Synco 200 family (specifically part of the RWR… series). It is primarily designed for the control of HVAC systems, including heating, ventilation, and cooling, as well as general process control in industrial and commercial buildings.

Product Detailed Description

The RWR462.10 is a versatile, stand-alone controller that manages plant components based on measured variables such as temperature, humidity, and pressure. It features a built-in user interface with an LCD display and buttons, allowing for local configuration without the need for additional tools. It supports both P (Proportional) and PI (Proportional-Integral) control actions to ensure stable system regulation.

Technical Parameters

Product Advantages

• Ease of Use: The menu-driven interface and pre-programmed application templates allow for rapid commissioning without complex software.
• Flexibility: Compatible with a wide variety of Siemens sensors (Ni1000) and standard 0…10 V active sensors, making it easy to integrate into existing systems.
• Compact Design: Small footprint saves space in electrical control cabinets.
• Reliable Control: The PI control algorithm minimizes hunting and ensures the setpoint is reached quickly and maintained accurately.

Important Considerations & Precautions

• Sensor Selection: Ensure the input configuration (jumpers or software settings) matches the specific sensor type (e.g., changing from Ni1000 to 0…10 V).
• Transformer Sizing: When powering multiple RWR units, ensure the 24 V AC transformer is sized correctly to handle the combined VA load.
• Signal Interference: Low-voltage sensor cables should be run separately from high-voltage power lines (110/230 V) to prevent electromagnetic interference.
• Mounting Orientation: For optimal heat dissipation, the unit should be mounted horizontally on a standard DIN rail.

Product Applications

The RWR462.10 is widely used in the following scenarios:

• HVAC Systems: Controlling mixing valves for heating circuits or modulating dampers in air handling units (AHUs).
• Chilled Water Control: Regulating the flow of chilled water based on room or return-air temperature.
• Pressure Regulation: Managing fan speeds via Variable Frequency Drives (VFDs) using the 0…10 V analog output.
• Industrial Processes: Maintaining constant temperatures in small-scale industrial drying or cooling applications.
