Technical Parameters of Metso D201477L AOI4C Analog Output Module
1. General Overview
The Metso D201477L AOI4C is an analog output module designed for industrial control systems. It serves as a crucial interface between the control logic and analog devices in the process, enabling precise and reliable signal transmission.
2. Output Characteristics
- Number of Channels: It features 4 analog output channels. This allows for the simultaneous control of multiple analog devices, such as valves, actuators, or variable – speed drives, providing flexibility in system design and operation.
- Output Range:
- The module typically supports a configurable output range. Common ranges include 0 – 10 V DC and 4 – 20 mA. The 0 – 10 V DC range is often used for applications where a linear voltage signal is required, such as in some types of sensors or displays. The 4 – 20 mA range is widely adopted in industrial automation due to its noise immunity and the ability to detect line breaks (a 0 mA signal indicates a fault).
- Accuracy: It offers high – accuracy analog output. The accuracy is usually specified as a percentage of the full – scale range. For example, it may have an accuracy of ±0.1% of the full – scale output, ensuring that the actual output signal closely matches the intended control signal.
- Resolution: The resolution of the analog output is an important parameter. It indicates the smallest change in the output signal that the module can generate. A higher resolution means finer control over the connected analog devices. The D201477L AOI4C often has a 12 – bit or higher resolution, allowing for precise adjustments of the output signal.
3. Power Supply
- Input Voltage: It requires a specific input voltage for operation. The typical input voltage range may be 24 V DC ±10%. This wide voltage tolerance provides some flexibility in power supply selection and helps to ensure stable operation even with minor voltage fluctuations in the industrial environment.
- Power Consumption: The module has a relatively low power consumption, which is beneficial for reducing energy costs and heat generation in the control cabinet. The exact power consumption value depends on the number of active channels and the output load, but it is generally designed to be energy – efficient.
4. Communication and Integration
- Bus Interface: The AOI4C module is designed to integrate with Metso’s control systems through a specific bus interface. This interface allows for seamless communication between the module and the central control unit, enabling real – time data exchange and control commands.
- Protocol Support: It supports standard industrial communication protocols, ensuring compatibility with a wide range of industrial automation equipment. The protocols may include Modbus, Profibus, or other proprietary protocols used in Metso’s systems.
5. Environmental Specifications
- Operating Temperature: The module can operate within a wide temperature range, typically from – 20°C to + 60°C. This allows it to be used in various industrial environments, including factories, power plants, and outdoor installations where temperature conditions may vary.
- Humidity Range: It can withstand a relative humidity range of 5% to 95% (non – condensing), ensuring reliable operation in humid industrial settings.
- Shock and Vibration Resistance: The D201477L AOI4C is built to withstand shock and vibration levels commonly encountered in industrial applications. It meets relevant industrial standards for shock and vibration resistance, minimizing the risk of damage during transportation, installation, and operation.
6. Protection Features
- Overvoltage Protection: The module is equipped with overvoltage protection circuits to prevent damage from voltage surges in the power supply or output lines. This helps to ensure the long – term reliability of the module and the connected analog devices.
- Short – Circuit Protection: It has short – circuit protection on the output channels. In the event of a short – circuit, the module will automatically limit the current or shut down the output to protect itself and the connected devices from damage.
In conclusion, the Metso D201477L AOI4C analog output module is a reliable and high – performance component for industrial control systems, offering precise analog output, good environmental resilience, and comprehensive protection features.
