CBE DS Powerblock Series

Overview

The CBE DS Powerblock Series is a modular electrical distribution system commonly used in motorhomes and caravans. The system consists of a distribution board and intelligent control panels (such as the PC320 display) that interface via a simple pin-switching and analog signaling interface.

Hardware Architecture

System Components

1. Distribution Board (DS-300)

   • Passive electrical distribution with relay-controlled outputs
   • 16-pin socket for display connection
   • Relays activated by ground switching from display

2. Control Panel (e.g., PC320)

   • Intelligent controller with user interface
   • Sends control signals to activate relays on distribution board
   • Handles all system logic and user interaction
   • Evaluates sensor signals (forwarded from distribution board)

Pin Configuration and Control Interface

The CBE DS Powerblock Series uses a simple electrical interface with no digital communication protocol. All control and monitoring is accomplished through direct pin switching and analog voltage levels.

The connection between the distribution board and the display panel uses a TE Connectivity AMPMODU MOD II 16-pin connector. The connector is a dual-row configuration with 2.54mm (0.1") pitch, compatible with standard MOD II mating connectors. Available variants:

• 280390-2: Right-angle connector
• 280385-2: Straight connector

On the PCB, this socket is designated as J9.
