ABB DSQC 313 3HAB3700-1-12 Brake Release Unit

ABB Brake Release Unit DSQC 313 3HAB3700-1-12 provides precise electrical control to release the holding brakes on ABB robot axes, enabling controlled startup and positioning when commanded by the automation system and ensuring the brake is released reliably during motion. This brake-release solution is part of ABB's industrial automation portfolio, designed to interface with ABB robotics and drive systems and to be installed proximal to axis brakes. In typical ABB installations such as the IRB 6730, brake release units connect to the robot via the R1.MP connector; energizing the brake coil uses 24 V on pin 11 and 0 V on pin 12, and incorrect wiring can cause all brakes to release simultaneously and unpredictably. ABB manuals describe the brake release unit’s placement near the axis brake and outline safe operation during release. Related ABB products in the same family include the Advanced Brake Release Unit (3HAC046642-001), illustrating ABB’s consistent approach to reliable brake control in industrial automation. Documents and manuals for ABB robotics—such as the IRB 1300 and other IRB models—show brake release units as standard components, with wiring and location details that help serviceability and safety during maintenance.
