System compatibility

XVME-260 belongs to XYCOM XVME series relay output 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

Discrete field load control for VME control rack.

32 independent relay contact channels,used to switch external solenoid valves,alarm lamps and auxiliary relays.

Supports output status readback through VME bus,real-time monitoring of actual relay state.

All relays keep normally open at power-up to meet safety interlock requirements.

Varistor surge protection for inductive loads,reduce contact damage.

Transmit relay status feedback to main CPU over VME backplane.

Onboard self-test for relay driving circuit,contact status detection,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-260 card into empty double-height VME slot,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Connect field load wiring to front panel connector.

Power on chassis,run hardware self-test.

VME CPU scans bus,identifies the board and starts relay output control.

Interface

VME P1 backplane connector,front panel field wiring terminal,LED indicators:PASS,FAULT.

Feature

Double height VME relay contact output board,XYCOM XVME series.

300VDC isolation between relay field side and VME backplane,suppress ground loop noise.

Individual channel relay,NO contact design,safe power-on state.

Built-in varistor absorption circuit,suitable for inductive loads.

Software readback function to verify relay switching state.

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:relay drive circuit damage or VME bus communication failure;

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

Relay no pull-in:check external load power supply and wiring continuity;

Intermittent contact failure:check aging of relay contacts and surge protection components

.

Product Brief

XYCOM XVME-260 is legacy VMEbus 32-channel relay contact digital output module.

It provides isolated relay contact switching control for VME control rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
