System compatibility

XVME-530 belongs to XYCOM XVME series isolated analog 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

Isolated analog control signal output for VME control rack.

8 independent 12-bit DAC channels,convert digital commands from VME CPU into analog voltage or 4~20mA current signals.

Each channel equipped with optoelectronic isolation to block common-mode noise between field side and VME backplane.

Support voltage/current mode configuration via hardware jumper.

Synchronous multi-channel update function for coordinated actuator control.

Support output readback function to monitor actual output value.

Transmit digital control data from VME backplane to isolated analog front-end circuit.

Onboard self-test for DAC circuit,isolation circuit,analog output stage,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-530 card into empty single-slot VME position,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Configure each channel for voltage or current mode.

Connect actuator/control valve wiring to front panel header.

Power on chassis,run hardware self-test.

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

Interface

VME P1 backplane connector,front panel analog output header,LED indicators:PASS,FAULT.

Feature

Single slot 6U VME 8-channel isolated analog output board,XYCOM XVME series.

300V channel-to-bus opto-isolation,suppress ground loop interference from field instruments.

12-bit high resolution DAC,guaranteed monotonicity for closed-loop process regulation.

Support mixed voltage and current signal configuration on different channels.

Single or synchronous multi-channel update for coordinated motion/process control.

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:DAC or isolated analog front-end circuit damage,VME bus communication failure;

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

Output value drift:check load impedance,shield grounding and wiring resistance;

No analog output:verify channel voltage/current jumper setting and field loop wiring continuity.

Product Brief

XYCOM XVME-530 is legacy VMEbus 8-channel 12-bit isolated analog output module.

It provides isolated analog regulation signals for valves and actuators in VME control rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
