ABB 3BHE036346R0102 CBA Splitter Board Small F3

Module Overview

The ABB 3BHE036346R0102 is a highly specialized, compact signal distribution module officially designated as the CBA Splitter Board, Small, F3. Functioning as a high-density Control Board Assembly (CBA), this module operates strictly within the system control, modulation, and signal distribution layer rather than the power conversion layer. Engineered for advanced industrial drive networks and excitation enclosures, this small form-factor splitter motherboard takes a single master control input—such as dynamic pulse-width modulation (PWM) commands, synchronization clocks, or communication diagnostic buses—and splits it seamlessly into multiple parallel, synchronous output channels with zero propagation delay. This ensures perfect real-time data execution across redundant phase modules or separate gate drivers within the system architecture.

Functional Attributes

• Deterministic Signal Splitting: Multi-casts master reference inputs into synchronized sub-signals, ensuring uniform gate firing and preventing torque ripple or phase asymmetry.
• Control Board Assembly (CBA) Standard: Mates natively with upper-level processing networks, establishing high-integrity low-voltage logic links away from high-power interference zones.
• Small Form-Factor Engineering: Features a high-density component layout designed to fit compressed vertical profiles, saving critical rail mounting space inside high-density control enclosures.
• Frame Size 3 (F3) Optimization: Specifically tailored for ABB Frame Size 3 cabinet architectures, matching exact mounting hole locations, physical spacing constraints, and electrical terminal bus specifications.

Target Deployments

• Frame Size 3 (F3) Drive Assemblies: Deployed as the dedicated hardware signal splitter platform within standard F3 modular converter cubicles.
• High-Power Excitation and Rectifier Systems: Used to mirror crucial phase synchronization feedback loops across separate tracking or protective channels.
• Multi-Drive Phase Configurations: Installed alongside primary processors to multi-cast timing commands to parallel-connected inverter modules.

Technical Specifications

On-Site Field Replacement Protocol

1. 1 Affix an approved ESD grounding strap to your wrist and attach the ground clip to a bare metallic point on the system chassis before opening the static shielding.
2. 2 Carefully map and tag each incoming master signal link and the corresponding split output wire harnesses to avoid any incorrect phase tracing during re-installation.
3. 3 Remove the mounting fasteners from the compact F3 chassis standoffs, pull the old board out, and fit the new splitter unit squarely onto the designated mounting points.
4. 4 Secure all retention fasteners to establish a robust physical frame ground. Re-insert the data connections and verify signal continuity before introducing auxiliary system power.
