Description

DSQC668 3HAC028179-001: Product Overview
The ABB DSQC668 (3HAC028179-001) is a DeviceNet communication adapter designed for integration with ABB IRC5 series robot controllers. Its role is to serve as a protocol gateway, enabling the controller to interface with DeviceNet-enabled distributed I/O modules, sensors, and actuators in robotic automation systems. In a typical setup, the IRC5 controller uses this module to exchange discrete I/O signals (e.g., start/stop commands, status feedback) with peripheral devices, ensuring synchronized operation of the robot and its associated tooling.
Functionally, the adapter processes 16 digital I/O channels (8 inputs, 8 outputs) via the DeviceNet protocol (up to 500 kbps), supporting both cyclic data exchange for real-time control and acyclic messages for diagnostics. It belongs to the IRC5 controller accessory family, a platform renowned for its modular architecture, compatibility with ABB RobotStudio simulation software, and seamless integration with factory automation networks. Benefits of this platform include reduced wiring complexity through standardized fieldbus communication, simplified system expansion via plug-and-play modules, and unified configuration workflows that minimize commissioning time.

Core Features & Customer Value​
The DSQC668 3HAC028179-001 addresses key challenges in robotic I/O integration. Its 16-channel density (8 in/8 out) reduces the need for multiple adapters in systems with moderate I/O requirements, such as a welding robot needing end-effector sensors and pneumatic valve controls. This consolidation simplifies wiring harnesses and lowers material costs.
Galvanic isolation (500V AC) protects the IRC5 controller from ground loops and voltage transients common in industrial environments, ensuring signal integrity for critical operations like part presence detection. Configurable sinking/sourcing inputs accommodate diverse field devices without external converters, streamlining retrofits of legacy sensors.
Hot-swap capability allows replacement without shutting down the robot, minimizing downtime during maintenance. Built-in diagnostics (LED indicators for power, communication, and I/O status) enable quick fault identification; for example, a faulty proximity switch can be isolated via error codes without disrupting production. Integration with ABB RobotStudio software permits virtual commissioning of I/O mappings, reducing on-site configuration time by 15-20%.
Typical Applications​
The DSQC668 3HAC028179-001 is deployed in IRC5-controlled robotic systems requiring DeviceNet communication. In an automotive assembly plant’s welding line, it connects an IRC5 controller to 8 weld gun proximity switches (inputs) and 8 pneumatic cylinder valves (outputs), synchronizing spot welding with part positioning.
In an electronics manufacturing facility, the adapter interfaces a pick-and-place robot’s controller with DeviceNet-linked vacuum sensors (inputs) and gripper actuators (outputs), ensuring precise component handling. Its 0°C cold-start capability supports climate-controlled cleanrooms.
In a logistics warehouse, a palletizing robot uses the module to communicate with DeviceNet I/O stations monitoring stack height sensors (inputs) and conveyor start/stop commands (outputs), optimizing throughput in high-volume operations.
