System compatibility

XVME-531 belongs to XYCOM XVME series high density 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

High density analog control signal output for VME control rack.

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

XVME-531/2 equipped with 500V optoelectronic isolation to block common-mode noise and ground loop interference between field side and VME backplane.

Each channel individually configurable for voltage or current output mode.

Synchronous multi-channel update for coordinated multi-valve or actuator control.

Support per-channel gain and offset calibration to guarantee output precision.

Transmit digital control data from VME backplane to 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-531 card into empty double-height 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 50pin 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 50pin analog output header,LED indicators:PASS,FAULT.

Feature

Double height 6U VME high density 16-channel analog output board,XYCOM XVME series.

Two variants for selection,/2 version with 500V channel-to-bus opto-isolation.

12-bit high resolution DAC,monotonic output for closed-loop process regulation.

Support synchronous multi-channel update for simultaneous actuator adjustment.

Independent offset and gain calibration for each 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:DAC or 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,recalibrate gain and offset;

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

Product Brief

XYCOM XVME-531 is legacy VMEbus 16-channel 12-bit analog output module with optional 500V isolation.

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