System compatibility

XVME-103 belongs to XYCOM XVME series multi-type memory module.

It installs in XYCOM VME chassis and cooperates with XVME series CPU and I/O modules.

Compatible with turbine,compressor and legacy DCS control systems via VME bus.

Commonly used for power plant,oil & gas,petrochemical old equipment maintenance and spare replacement.

Function

Storage expansion for XVME VME controller rack.

Supports RAM,EPROM,Flash,EEPROM multiple memory media to store control program,firmware and process data.

Onboard battery backup,realize data preservation when power failure.

Two independent memory banks,support jumper configuration for different memory capacity.

High-speed data reading and writing through VME backplane bus.

Onboard self-test for memory chip,battery monitoring circuit and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-103 card into empty VME slot,tighten front panel fixing screw.

Set memory bank jumpers according to actual configuration.

Power on chassis,run hardware self-test.

Controller identifies memory module and activate expanded memory space.

Interface

VME P1 backplane connector,LED indicators:PASS,FAULT,BATTERY LOW.

Feature

Single height VME multi-function memory board,XYCOM XVME series.

8 memory sockets,two independent configurable memory banks.

Built-in battery low voltage monitoring and alarm function.

Industrial grade memory chip,stable data storage under vibration environment.

VME slave interface,easy plug-in installation.

Discontinued obsolete VME module,supply only for old production system spare replacement.

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

FAULT LED on:memory chip damage or VME bus communication failure;

BATTERY LOW LED on:backup battery voltage insufficient,need battery replacement;

Cannot be identified by CPU:check VME backplane contact and address jumper setting;

Data loss after power off:check backup battery and battery circuit.
