System compatibility
XVME-224 belongs to XYCOM XVME series isolated 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
Relay and field actuator driving for VME control rack.
32 opto-isolated relay driver channels,drive external relays,solenoid valves and alarm indicators.
Receive control command from VME main controller and switch each channel independently.
Support output status readback function to verify field load state.
Power-on safe state,all output channels keep off after reset.
Support VME interrupt when channel fault detected.
Onboard self-test for output optocoupler,drive circuit,data bus and VME bus interface fault inspection.
Installation
Power off VME chassis.
Insert XVME-224 card into empty VME slot,tighten front panel fixing screw.
Set base address and interrupt level via board jumpers.
Connect field relay 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
Single height VME isolated relay driver output board,XYCOM XVME series.
2500V high optical isolation between field side and VME backplane,eliminate ground loop interference.
Built-in inductive load surge suppression,suitable for relay and solenoid loads.
Output status readback,real-time feedback of actual channel state.
Overcurrent protection for each individual channel.
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;
Relay cannot pull in:check external field power supply and wiring continuity;
Intermittent output failure:check surge suppression and shielding grounding.
Product Brief
XYCOM XVME-224 is legacy VMEbus 32-channel opto-isolated relay driver digital output module.
It provides high-isolation relay driving output for VME control rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
