                      • Model: DSQC350A (often appears in series as “DSQC 350 / DSQC350A”)

                      • Part Number: e.g., 3HNE00025‑1/17 variants.

                      • Type: Remote I/O Unit — Used to expand input/output channels in control cabinets or robotic/automation systems.

                      • Physical / Weight: Some used‑unit listings indicate approx. 0.55 kg (550 g) weight.

                      • Functional Overview: The module acts as a remote I/O node in control systems (e.g., robot controllers or automation racks) to gather digital/analog I/O signals from the field and interface them with the main controller.

                      • Interface / Communication: Although specific interface details are not fully published for this exact model, remote I/O units commonly support field‑bus or network communication protocols (such as DeviceNet, Profibus, EtherNet/IP) to link with the main control system.

                      Advantages & Features

                      • Expanded I/O capability: Allows a system to distribute I/O closer to field devices, rather than concentrating all I/O in the main cabinet — improves layout and flexibility.

                      • Reduced wiring cost: By placing the I/O module near field devices, you reduce the need for long runs from the main control rack to each device, improving efficiency.

                      • Ideal for distributed control systems: In robotic systems and production lines, the module serves as a remote node communicating with the main controller — enhancing modularity.

                      • Brand reliability & ease of replacement: As an ABB‑branded remote I/O module, offers system compatibility and relatively straightforward replacement/integration.

                      • Well‑established in industry: Has been used in many automation and robotics installations, giving a healthy aftermarket for spare parts.

                      Application Areas

                      • Robot workstations and control cabinets: Used as remote I/O expansion modules in robot control systems.

                      • Automation production lines and assembly lines: Field devices (sensors, actuators) connect through remote I/O modules to the main controller.

                      • Logistics, material handling, packaging systems: These environments often require distributed I/O layout near field devices.

                      • Legacy system maintenance / spare parts: For installations still using older ABB remote I/O architectures, this unit serves as a replacement or spare.

                      Precautions

                       

                      • When purchasing, ensure you match the full model (“DSQC350A” or “DSQC350”) plus correct part number (e.g., 3HNE00025‑1/17) to ensure compatibility with your existing system.

                      • Verify installation environment and interface standards: The remote I/O module may require specific bus/network protocols supported by your system.

                      • On installation or replacement, ensure power is disconnected, employ anti‑static protection, ensure proper ventilation and wiring practices.

                      • For used or surplus units, investigate the unit’s service history, test status, damages or missing parts.

                      • When upgrading or expanding a system, if moving to newer communication protocols/field‑buses, be aware older remote I/O modules may have compatibility limitations—evaluate overall system architecture.

                      • Ensure environmental conditions (temperature, humidity, vibration, dust) are suitable for the I/O unit reliability.
