ABB 7B028120 Definite Purpose - DMCBO-50 90V Brake
Part Number: 7B028120
Quick Summary
Definite Purpose 7B028120 provides brake-enabled control for 90V motor systems in industrial panels. Engineers often face space constraints, retrofit headaches, and unreliable brake integration—this module streamlines installation and reliability. While the data shows US origin, 0-day lead times, active stock, and warranty terms, it does not list CE, SIL, or IP certifications; typical ABB components support standard safety practices in panel enclosures. Designed for ABB compatibility and double C-face mounting, it offers predictable performance, reduced downtime, and straightforward procurement for automation projects.

FAQs
Yes. The 7B028120 is designed for 90V motor systems and employs a double C-face mounting scheme that aligns with common ABB drive assemblies and motor frames. Verify frame size (56) and enclosure clearance during layout, and confirm mounting hole patterns to ensure a clean, vibration-resistant installation. The product is stocked for quick procurement, reducing commissioning delays.
The unit provides 22 in-lb of holding torque and uses a double C-face mounting layout suitable for 56-frame motors. With a footprint of approximately 22.403 cm in length, 23.19 cm in height, and 24.79 cm in width, it fits compact control panels while maintaining robust brake performance. Weight is about 3.655 kg, aiding stable enclosure placement and vibration resistance.
Industries such as packaging, material handling, and machine tooling benefit from reliable brake control in panel-mounted drives. The DMCBO-50 brake module supports quick stop and stall prevention in 90V motor systems, improving line uptime, reducing mechanical wear, and enabling safer automated cycles in conveyors, presses, and automated tooling setups.
The provided data does not explicitly list CE, SIL, or IP certifications for 7B028120. It does note United States origin and active stock, with standard warranty terms. For regulated environments or highly certified facilities, confirm with ABB or the distributor about current certification status and any required third-party approvals before installation in UL-listed or CE-marked panels.
ROI benefits arise from reduced downtime, faster procurement, and predictable maintenance with a compact, panel-ready brake solution. The warranty policy and 0-day lead time support rapid replacements, minimizing production interruption. In terms of maintenance, expect routine inspection of brake wear indicators and mounting integrity; the module’s weight and footprint simplify enclosure cooling and service access.
