ABB DSQC352 Profibus Module

Overview

ABB DSQC352 is a digital input/output module specially designed for industrial robot control systems, belonging to the peripheral equipment of ABB's robot IRC5 controller series. It is mainly responsible for digital signal interaction between industrial robots and external equipment, capable of accurately receiving digital input signals from sensors, buttons, and other devices, while reliably outputting control signals to actuators, indicator lights, and other devices. It is a key component for realizing collaborative work between robots and peripheral equipment, providing solid signal transmission guarantee for the efficient and stable operation of industrial robot automated production lines.

Technical Parameters

• 
  

• Input/Output Channels: Equipped with 16 digital input channels and 16 digital output channels, the number of input and output channels is balanced, which can meet the signal interaction needs in most industrial robot scenarios. The input channels can receive standard DC 24V digital signals with a short response time, usually no more than 1ms, ensuring that the state changes of external equipment can be quickly captured; the output channels can provide DC 24V driving voltage, with each output channel current up to 0.5A and total output current not exceeding 8A, which can stably drive small relays, solenoid valves, and other actuators.

• Power Supply Specifications: Powered by DC 24V, compatible with the power supply systems commonly used in industrial robots. The allowable fluctuation range of the power supply voltage is DC 20.4V - 28.8V, adapting to slight fluctuations of power supply voltage in industrial sites. The power consumption is low, usually not exceeding 5W during normal operation, helping to reduce the overall energy consumption of the system.

• Electrical Isolation: Electrical isolation design is adopted between input channels and output channels, and between each channel and the internal circuit of the module, with an isolation voltage of 2500V AC. This effectively avoids electrical interference between different channels and between the module and external equipment, ensuring the accuracy of signal transmission and the stability of the module's work, especially suitable for industrial sites with complex electromagnetic environments.

• Environmental Adaptability: The operating temperature range is 0℃ - 60℃, which can work stably in the common temperature environment of industrial production workshops. The relative humidity is 5% - 95% (non-condensing), which can adapt to humid working environments without being affected by humidity changes. At the same time, it has a certain anti-vibration ability, meeting the IEC 60068-2-6 standard, and can resist the vibration impact generated when the robot is working.

• Physical Specifications: Adopting a compact modular design, the size is approximately 100mm×80mm×60mm, and the weight is about 0.8kg. It occupies a small space, making it easy to install inside the robot control cabinet or on the equipment mounting frame around it. The installation method is DIN rail mounting, compatible with industrial standard installation methods, and the installation process is simple and fast, allowing quick integration into the robot control system.

Functional Features

• 
  

• Efficient Signal Interaction: The 16-in 16-out channel configuration provides sufficient interfaces for signal interaction between the robot and external equipment, capable of processing status signals and control commands from multiple external devices at the same time. For example, in a robot welding workstation, the input channels can receive the clamping signal of the welding fixture and the signal of the workpiece in-place sensor, and the output channels can control the start-stop of the welding gun and the operation of the cooling fan, etc., realizing efficient collaboration between the robot and peripheral auxiliary equipment and improving the production rhythm.

• Reliable Signal Transmission: The electrical isolation design and stable circuit structure ensure the reliability of signal transmission. Even in the presence of strong electromagnetic interference in industrial sites, it can effectively avoid signal distortion or misoperation. The fast response characteristic of the input channels enables the state changes of external equipment to be timely fed back to the robot controller, and the stable driving ability of the output channels ensures the reliable action of the actuators, reducing production interruptions caused by signal problems.

• Flexible System Expansion: When industrial robots need to connect more external equipment, the number of input and output channels can be expanded by combining multiple DSQC352 modules to meet the needs of automated production lines of different scales. The module supports fast communication with the ABB IRC5 controller, enabling collaborative work of multiple modules without complex configuration, improving the flexibility and expandability of the system.

• Convenient Status Monitoring: The module is equipped with intuitive LED status indicators, with each input and output channel corresponding to an independent indicator. The input channel indicator lights up when receiving an effective signal, and the output channel indicator lights up when outputting a control signal. This facilitates operators and maintenance personnel to quickly judge the working status of each channel, timely detect and troubleshoot signal transmission faults, and shorten the fault handling time.
