VME P2 expansion-layer backplane design, incorporating 10 Power Bugs to electrically bridge the VME P1 main backplane and the VPBL expansion backplane.

Ensures continuous and reliable signal and power transmission between the main control rack and expansion modules.

Contains no active electronic components—functions purely as a hardware interconnection and power distribution backplane, maximizing reliability.

Key Hardware Elements

12-pin Mate-N-Lok power connector for main system power input.

34-pin EXJV ribbon connector for external expansion signal routing.

J2 expansion slot, compatible with LS2100 series plug-in modules.

Purely passive design with copper interconnects for signal and power routing.

Core Functions and Typical Applications

Expansion Interconnection

Overcomes VME main backplane slot limitations by providing additional expansion interfaces.

Enables external signal exchange between the LS2100 static starter and Mark V control modules, including:

Start/stop commands

Status and feedback signals

Power Distribution

Uses Mate-N-Lok connectors and Power Bugs to distribute system power evenly and reliably.

Reduces the risk of expansion module failures caused by voltage drop or power instability.

Signal Isolation and Integrity

Provides physical separation between the main VME control signals and externally expanded signals.

Minimizes the impact of external electrical interference on the core control logic, improving system robustness.

Typical Applications

LS2100 gas turbine static starter control expansion areas.

Commonly used with:

DS200TCQAG1B (Analog I/O Board)

DS200TCEAG1BTF (Overspeed Protection Board)

Suitable for power generation systems with high demands for starter control scalability, reliability, and external signal integration.
