B&R 8B0C0320HW00.002-1 ACOPOSmulti Auxiliary Supply Module

Product Overview

The 8B0C0320HW00.002-1 (8B0C0320HW000021) is a specialized auxiliary supply module designed for the B&R ACOPOSmulti drive system. This unit provides the necessary stabilized control power to the drive network, ensuring that logic circuits, communication interfaces, and safety functions remain active even when the primary high-voltage DC bus is discharged. Engineered for high-availability industrial environments, this module is critical for applications in automated assembly, pharmaceutical packaging, and CNC systems where maintaining control-side synchronization is vital for safety and rapid restart capabilities. Its robust construction supports the "cold-plate" or large-scale mounting configurations typical of the ACOPOSmulti series, contributing to a reliable and thermally efficient cabinet design.

Technical Configuration

This auxiliary module is built to provide a bridge between standard industrial power sources and the specialized internal requirements of the ACOPOSmulti backplane.

• Logic Power Stabilization: Converts standard cabinet power into a high-precision supply for the inverter and power supply modules, shielding sensitive control electronics from voltage dips.

• Defined Switching Thresholds: Features precise input logic levels (Low $< 5$ V; High $> 15$ V) for status monitoring and control signals, ensuring compatibility with standard industrial sensors and safety controllers.

• Industrial Grade Protection: Rated at IP20, the front-side design is optimized for safe installation within protected control cabinets, providing effective shielding against solid foreign objects.

• High Power Density: Despite its substantial $5.5$ kg build, the module is designed for a slim mounting profile to maximize available space on the ACOPOSmulti backplane.

Technical Specifications

FAQs

What is the primary function of the 8B0C0320HW00.002-1?

This module supplies the "control voltage" for the drive system. It ensures that the brain of the ACOPOSmulti system (the logic and communication) stays powered up regardless of whether the motors are receiving high-voltage power.

Is this module compatible with all ACOPOSmulti systems?

Yes, it is designed for the ACOPOSmulti platform; however, you must verify the total power requirements of your drive lineup to ensure this single auxiliary module provides sufficient current for all connected inverter slices.

What happens if the input voltage exceeds 30 VDC?

The module is rated for a maximum of $30$ VDC. Exceeding this threshold can lead to overvoltage stress on the internal regulator circuits and may trigger an integrated protection shutdown or cause hardware damage.

Engineering Installation and Power Safety Guidelines

• Mounting Alignment: When mounting the module into the ACOPOSmulti rack, ensure that the rear-side connections to the backplane are perfectly aligned. Given the $5.5$ kg weight, improper seating can cause mechanical stress on the communication pins, leading to intermittent system errors.

• Voltage Quality: While the module accepts up to $30$ VDC, for optimal MTBF, it is recommended to use a stabilized $24$ VDC power supply with low ripple and noise. This prevents thermal stress on the module's internal filtering components.

• Grounding and Shielding: Ensure the mounting plate is properly grounded to the cabinet's central earth point. This module acts as a reference point for many control signals, and a poor ground connection can introduce noise into the drive's communication bus.

• Heat Dissipation: Due to the internal power conversion, the module will generate heat during operation. Maintain the specified clearances at the top and bottom of the ACOPOSmulti rack to allow for natural or forced convection cooling.
