VE3007

Description

2. Applications

• Chemical and Petrochemical Industries: As shown in the above case, it is used for ventilation control in chemical storage facilities, refineries, and petrochemical plants. It helps to maintain a safe working environment by monitoring and adjusting the ventilation systems according to the gas concentrations.
• Pharmaceutical Industry: In pharmaceutical manufacturing plants, the VE3007 can be used to control the air – handling units in cleanrooms. It ensures the proper filtration and circulation of air to meet the strict air quality requirements for drug production.
• Food Processing Industry: For food processing facilities, it can be used to control the ventilation in areas where odors, moisture, or dust need to be removed. It helps to maintain a hygienic and comfortable working environment.

3. Weight and Dimensions

• Weight: The VE3007 weighs approximately 0.9 kg. Its relatively light weight makes it easy to install and handle during the setup and maintenance of the ventilation control system.
• Dimensions: It has dimensions of about 140 mm in length, 100 mm in width, and 35 mm in height. These compact dimensions allow it to be easily installed in standard electrical enclosures or on DIN rails, saving space in control panels.

4. Features

• Multi – Sensor Compatibility: The VE3007 can be connected to a variety of gas sensors, such as oxygen sensors, combustible gas sensors, and toxic gas sensors. It can also interface with temperature and humidity sensors to provide comprehensive environmental monitoring.
• Intelligent Control Algorithms: It is equipped with intelligent control algorithms that can analyze the sensor data and make optimal decisions for ventilation control. For example, it can adjust the fan speed based on the real – time gas concentration and the size of the ventilation area.
• User – Friendly Interface: It has a user – friendly interface that allows users to easily configure the system parameters, view the sensor data, and set up alarm thresholds. This makes it convenient for operators to manage the ventilation system.

5. Stability and Reliability

• Robust Design: The VE3007 is built with a durable housing that provides protection against dust, moisture, and electrical interference. This makes it suitable for use in harsh industrial environments, such as chemical plants with high levels of corrosive gases.
• Redundant Power Supply: Some models of the VE3007 may support a redundant power supply. In case of a power failure, the redundant power source can ensure the continuous operation of the device, preventing the ventilation system from shutting down unexpectedly.
• Error – Detection and Self – Recovery: It has built – in error – detection mechanisms that can detect sensor malfunctions, communication errors, and other faults in real – time. It can also perform self – recovery operations, such as restarting a malfunctioning module or switching to a backup communication path, to maintain system stability.

6. Parameter Specifications

• Power Supply: It operates on a 24V DC power supply, with an allowable voltage range of 21.6V to 26.4V. This wide voltage range ensures stable operation even in the presence of small power fluctuations.
• Input/Output Channels:
  • Analog Inputs: It has 4 analog input channels, which can accept signals from gas sensors, temperature sensors, and other analog – type sensors.
  • Digital Inputs/Outputs: There are 8 digital input channels for detecting the status of switches and other digital sensors, and 6 digital output channels for controlling relays, solenoid valves, and other digital devices.
• Communication Interface: It supports communication via Modbus RTU over RS – 485, which is a widely used industrial communication protocol. This allows it to communicate with other devices in the control network, such as programmable logic controllers (PLCs) and human – machine interfaces (HMIs).
• Sampling Rate: The sampling rate for sensor data can be configured, with a maximum sampling rate of up to 10 samples per second, ensuring timely and accurate monitoring of the environmental parameters.
