System compatibility

XVME-540 belongs to XYCOM XVME series integrated analog AIO 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

Integrated analog signal acquisition and control output for VME control rack.

12-bit ADC collects pressure,temperature,flow sensor analog signals,32SE /16DI jumper configurable.

4 channel 12-bit DAC converts digital commands from VME CPU to analog voltage or 4~20mA control signals for valves and actuators.

Support 3B series signal conditioning interface for external signal conditioning modules.

Multiple sampling modes for different process acquisition requirements.

Support output readback function to verify analog output value.

Transmit field analog sampling data and receive control commands via VME backplane.

Onboard self-test for ADC,DAC,analog front-end,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-540 card into empty single-slot VME position,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Select single-ended or differential AI wiring mode,configure AO voltage/current mode.

Connect sensor and actuator wiring to front panel 50pin header.

Power on chassis,run hardware self-test.

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

Interface

VME P1 backplane connector,front panel 50pin AIO wiring header,LED indicators:PASS,FAULT.

Feature

Single slot 6U VME integrated AIO board,XYCOM XVME series.

Combine multi-channel analog input and analog output on one single VME card,save chassis slot resources.

12-bit high precision ADC/DAC,programmable input gain and signal range.

Support 3B signal conditioning system connection.

Differential input mode suppress common-mode noise and ground loop interference.

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:ADC/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;

AI reading unstable:check AI wiring mode,shield grounding and common-mode interference;

AO no output:verify AO voltage/current jumper setting and field loop wiring continuity.
