Overview
The ABB DSQC 239 Remote I/O Board is a legacy digital input/output and communication interface module for ABB robot controllers. This remote I/O board expands the number of digital input and output ports accessible for your robot controller, facilitating the connection of additional sensors and actuators. Designed for ABB S4C and S4C Plus robot controllers to manage external device signaling and data transmission.
Key Features
- Supports up to 16 inputs and 8 outputs for flexible I/O management.
- Features an RS-232 interface for seamless communication between the controller and the robot.
- Employs a communication protocol licensed from Allen-Bradley, specifically the RIO protocol.
- Compact design suitable for mounting in robot control cabinets.
- Robust construction for industrial environments.
Technical Specifications
- 64-pin connectors for main and auxiliary communication lines.
- LED indicators for input/output status monitoring.
- RS-232 serial communication interface.
- Legacy compatibility with ABB S3 (M91A or later) and S4C/S4C Plus controllers.
- Tested and verified for full operational functionality.
Typical Applications
The DSQC 239 Remote I/O Board is ideal for:
- Expanding sensor and actuator connectivity on ABB robot cells.
- Legacy system upgrades and I/O expansion without controller replacement.
- Manufacturing and assembly automation with multiple discrete I/O requirements.
- Integration with Allen-Bradley PLCs via RIO protocol.
