System compatibility
XVME-220 belongs to XYCOM XVME series digital 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
Field load driving and discrete control output for VME control rack.
32 opto-isolated open-collector output channels,drive relays,solenoid valves and indicator lights.
Receive control commands from VME main CPU and switch on/off each channel independently.
Onboard programmable scanner,support output state monitoring and state-change interrupt.
All outputs default off during power-up to satisfy safety requirement.
Transmit channel status feedback to main CPU over VME backplane.
Onboard self-test for output optocoupler,driving circuit,data bus and VME bus interface fault inspection.
Installation
Power off VME chassis.
Insert XVME-220 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 50pin ribbon connector.
Power on chassis,run hardware self-test.
VME CPU scans bus,identifies the board and starts digital output control.
Interface
VME P1 backplane connector,50pin ribbon cable terminal,LED indicators:PASS,FAULT.
Feature
Double height VME opto-isolated digital output board,XYCOM XVME series.
300V optical isolation between field side and VME backplane,eliminate ground loop interference.
Open collector sinking design,wide adaptability for different external load power supply.
Built-in surge and reverse voltage protection,prevent damage from field wiring fault.
Power-on safe state,all channels off when system reset.
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:output optocoupler damage or VME bus communication failure;
Cannot be identified by CPU:check VME backplane contact and base address jumper setting;
Channel cannot drive load:check external power supply,load wiring and output sinking current limit;
Intermittent output dropout:check shielding grounding and transient surge on field side.
Product Brief
XYCOM XVME-220 is legacy VMEbus 32-channel opto-isolated open collector digital output module.
It provides isolated discrete control output for relays and solenoids in VME control rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
