System compatibility

XVME-976 belongs to XYCOM XVME series expansion carrier module.

Directly compatible with XVME-654 CPU board;work with XVME-655 CPU with transition board XVME-978/1 or XVME-978/100;also used with XVME-690.

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

I/O mezzanine expansion carrier for XYCOM XVME VME CPU boards.

Provides PMC and PC/104 dual expansion sites to add extra peripheral functions.

Onboard DC regulator supplies stable 3.3V power for PMC modules.

Transmit local bus signals between host CPU and installed PMC/PC104 submodules.

Support various submodules for network,storage,serial communication and digital I/O expansion.

Realize system function upgrade without occupying extra independent VME slots.

Support hardware self-test for carrier and mounted mezzanine modules,fault displayed via LED indicator.

Installation

Power off VME chassis.

Insert XVME-976 card into empty 6U single-height VME slot,tighten front panel fixing screw.

Install PMC or PC/104 submodules onto corresponding sites on the carrier.

Set address and interrupt jumpers according to system configuration.

Connect field peripheral cables on front panel.

Power on chassis,run hardware self-test together with paired XVME CPU board.

Interface

VME P2 backplane connector,PMC connector,PC/104 stack connector,front panel peripheral port,LED indicators.

Feature

6U single slot VME expansion carrier board,XYCOM XVME series.

Dual mezzanine design,support both PMC and PC/104 standard submodules.

Built-in 3.3V power regulation circuit for PMC modules.

Multiple optional variants for different expansion requirements.

Modular design,easy to expand network,storage and serial interfaces.

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

Vibration resistant PCB design,suitable for turbine control cabinet.

Diagnostic

LED alarm on:mezzanine module fault,address jumper error,power abnormality or local bus signal failure;

Submodule no response:check mezzanine board installation,pin contact and jumper configuration;

VME communication failure:check P2 backplane contact and paired CPU setting.
