PLCs, Power Supplies & Others

The ABB DSQC223 functions as a specialized digital I/O printed circuit board for the ABB IRB 300 robot series. This board manages critical signal exchange between the robot controller and the manipulator’s peripheral systems. Consequently, it provides a reliable and compact interface for tooling, sensors, and workcell devices.

Core Technical Specifications

We engineered the ABB DSQC223 as a robust, panel-mounted circuit board for direct integration within the robot control cabinet. The table below details its essential physical and electronic parameters:

Dedicated I/O Architecture for the IRB 300

This circuit board provides eight opto-isolated digital inputs, which safely receive signals from limit switches and operator pushbuttons. Additionally, the DSQC223 features eight transistor outputs capable of driving small relays, pilot lights, or solenoid valves. Therefore, this single board offers complete, dedicated I/O for the specific needs of the IRB 300 robot.

Reliable Signal Processing with Optical Isolation

Each of the eight input channels on the DSQC223 includes optical isolation to protect the internal logic from electrical noise. This design proves essential in welding or forming applications where high currents can induce interference. As a result, the board guarantees accurate signal reading and stable robot operation in harsh environments.

Compact Form Factor for Cabinet Integration

ABB designed this PC board with a compact footprint of just 100 mm by 160 mm for efficient use of cabinet space. It mounts directly onto threaded standoffs inside the controller, ensuring a stable and vibration-resistant connection. Furthermore, its low profile allows for optimal airflow around other critical components.

Simplified Wiring and Connectivity

Two standard 20-pin flat cable headers provide the main connection points for all I/O signals to terminal blocks. This arrangement simplifies wiring and troubleshooting by keeping field wiring separate from the sensitive circuit board. Consequently, technicians can easily test signals or replace the board without extensive rewiring.

Long-Term Reliability in Industrial Use

We constructed the DSQC223 using high-quality components rated for continuous industrial operation. It functions reliably within a temperature range of +5°C to +50°C and withstands typical factory floor vibrations. The board’s robust construction ensures a long service life, minimizing downtime for your IRB 300 robot.
