DXA-205

Description

Parameter Specifications

1. Power Supply: The DXA – 205 operates on a 24V DC power supply. The power consumption is approximately 6 – 10W, designed to be energy – efficient for continuous operation in industrial or commercial settings.
2. Input/Output Channels: It features 5 analog input channels and 2 analog output channels. The analog input channels can accept signals in the range of 0 – 10V DC or 4 – 20mA DC, which are common output signals from various sensors such as temperature sensors, pressure sensors, and flow sensors. The analog output channels can provide output signals in the same ranges, allowing it to control actuators like variable – speed drives or proportional valves.
3. Communication Interface: It is equipped with a serial communication interface (RS – 485), supporting a data transfer rate of up to 115200 bps. It adheres to the Modbus RTU protocol, enabling seamless communication with other devices in an industrial network for data exchange and remote control.
4. Resolution: The analog input and output channels have a resolution of 12 – bit, which provides a reasonable level of precision for measuring and controlling analog signals.
5. Operating Temperature Range: Designed to function within a temperature range of – 10°C to 60°C. This wide temperature tolerance allows it to be used in various environments, from cold storage areas to warm industrial workshops.

Applications

1. Industrial Process Control: In manufacturing plants, the DXA – 205 can be used to monitor and control industrial processes. For example, it can measure the temperature and pressure of a chemical reactor using the analog input channels and adjust the flow rate of reactants through the analog output channels to maintain optimal process conditions.
2. HVAC Systems: In heating, ventilation, and air – conditioning (HVAC) systems, it can be used to measure the temperature and humidity of a building using sensors connected to the analog input channels. It can then control the operation of fans, heaters, and coolers through the analog output channels to maintain a comfortable indoor environment.
3. Renewable Energy Systems: In solar or wind power plants, it can monitor the power output, voltage, and current of the renewable energy sources using the analog input channels. It can also control the operation of power converters and inverters through the analog output channels to optimize the power generation efficiency.

Weight and Dimensions

1. Weight: Approximately 0.5 kg, which is relatively light and easy to handle during installation and maintenance.
2. Dimensions: It has a compact design, with dimensions of about 120mm (length) x 100mm (width) x 40mm (height). This small size allows it to be easily installed in control panels or other limited – space areas.

Features

1. Analog I/O Capability: The combination of analog input and output channels enables it to handle real – world analog signals, making it suitable for a wide range of applications that require analog measurement and control.
2. Modbus RTU Communication: The support for the Modbus RTU protocol on the RS – 485 interface allows for easy integration with other Modbus – compatible devices, facilitating the construction of comprehensive industrial control systems.
3. Cost – effective Solution: It offers a cost – effective solution for analog measurement and control tasks, especially for small – to medium – scale applications.

Stability and Reliability

1. Robust Construction: Built with high – quality components and a durable enclosure, it can withstand normal industrial vibrations, minor shocks, and dust.
2. Electrical Isolation: It provides electrical isolation between the analog input/output channels and the power supply, protecting the device from electrical interference and ensuring stable signal transmission.
3. Long – term Testing: Through long – term testing, it has been proven to have a reliable performance over time, with a low failure rate.
