ABB DSQC 633 Digital I/O modules

ABB DSQC 633

The 1000 Series is a digital I/O module designed for ABB robot controllers, such as the IRC5 and OmniCore. It is a key component in the robot system for connecting and controlling external devices, handling the input and output of digital signals.

1. Product Overview

The ABB DSQC 633 is a digital I/O module designed specifically for ABB’s robot controllers (such as the IRC5 and OmniCore). It is a key component in robotic systems for connecting to and controlling external devices, responsible for handling digital input and output signals.

• Product Family: DSQC 600 Series I/O Modules

• Primary Function: Digital Input / Digital Output

• Design Purpose: To be integrated into ABB robot systems as a standard, configurable I/O unit.

2. Core Functionality

The DSQC 633 module provides two types of channels:

• 8 Digital Input Channels:

  • Used to receive “on/off” or “high/low” signals from external devices.

  • Typical Applications: Detecting the status of sensors (e.g., limit switches, photoelectric sensors), receiving push button signals, reading safety door status, etc.

  • Input Voltage: Typically 24V DC.

• 8 Digital Output Channels:

  • Used to send “on/off” or “high/low” signals to external devices to control their actions.

  • Typical Applications: Controlling actuators such as relays, solenoid valves, indicator lights, and alarms.

  • Output Voltage: Typically 24V DC, with each channel capable of providing a specific drive current.

3. Key Features

• Plug-and-Play: As a standard ABB module, it can be easily inserted into a designated slot in the robot controller cabinet (e.g., an I/O slot on the main computer or drive unit) and is quickly configured via RobotWare software.

• DeviceNet Communication: The module communicates with the main robot controller via the DeviceNet fieldbus, ensuring high-speed and reliable data exchange. This is a widely used network protocol in industrial automation.

• Compact Design: The module is compactly designed, making it suitable for installation inside controllers with limited space.

• Status Indicators: The module is typically equipped with LED indicators to display power status, network communication status, and the status of each I/O channel, facilitating on-site debugging and troubleshooting.

• High Reliability: Designed for industrial environments, it offers strong noise immunity and stable operation.

4. Technical Specification Summary

• I/O Type: 8 x Digital Input, 8 x Digital Output

• Input Voltage: 24V DC (General specification, please refer to the manual for details)

• Output Voltage: 24V DC, Sink or Source current (Please refer to the manual for details)

• Communication Protocol: DeviceNet

• Power Supply: Via the DeviceNet connector or an external power supply (depending on the specific model and configuration)

• Installation: Plug-in module, installed inside the ABB controller

5. Application in Robotic Systems

In a typical robot workstation, the DSQC 633 acts as a “bridge”:

• Input Side: Connects to various field sensors, for example:

  • Part-in-place detection sensors

  • Gripper clamped confirmation sensors

  • Safety fence door lock switches

  • Start/Stop buttons from an operator pendant

• Output Side: Controls actuators within the workstation, for example:

  • Open/Close solenoid valves for grippers

  • Start/Stop relays for conveyors

  • Status indicator lights (Running, Fault, Complete)

  • Audio-visual alarms

6. Related Models and Considerations

• Configuration: Before use, the module’s DeviceNet address and I/O signals must be configured and mapped using ABB robot programming software (like RobotStudio). This allows them to be read from and written to within the robot program (using DI, DO instructions).

• Similar Models: ABB has other digital I/O modules, such as the DSQC 651 (also 8DI/8DO, but may use a different communication protocol), DSQC 652 (16DI/16DO), etc. The choice of model depends on the specific number of I/O points required and the communication protocol.
