System compatibility

XVME-505/2 belongs to XYCOM XVME series 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

Analog control signal output for VME control rack.

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

Drive field actuators,control valves and positioners with 4~20mA or voltage signals.

Each channel individually configurable for voltage or current output mode.

Support output readback function to verify actual analog output value.

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

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

Installation

Power off VME chassis.

Insert XVME-505/2 card into empty single-slot VME position,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Connect actuator/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 4-channel analog output board,XYCOM XVME series.

Dual signal output type,selectable voltage or 4-20mA current for each channel.

12-bit high resolution DAC,stable output for process regulation control.

Output readback function for loop monitoring and fault detection.

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 output 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 mode configuration and field loop wiring continuity.

Product Brief

XYCOM XVME-505/2 is legacy VMEbus 4-channel 12-bit analog output module.

It provides 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.
