System compatibility

XVME-203 belongs to XYCOM XVME series high-speed counter 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 speed pulse and encoder signal acquisition for VME control rack.

Support quadrature encoder signal decoding,position tracking and speed calculation.

Realize event counting,frequency measurement,period measurement and pulse width capture.

8 digital output channels for pulse or alarm signal output.

Support hardware interrupt to notify CPU once count target reached.

Transmit counting data and position information to main CPU over VME backplane.

Onboard self-test for counter circuit,encoder input port,data bus and VME bus interface fault inspection.

Installation

Power off VME chassis.

Insert XVME-203 card into empty VME slot,tighten front panel fixing screw.

Connect encoder and pulse signal wiring to front panel 50pin ribbon connector.

Power on chassis,run hardware self-test.

VME CPU scans bus,identifies the board and starts counter & encoder sampling operation.

Interface

VME P1 backplane connector,50pin ribbon cable terminal,LED indicators:PASS,FAULT.

Feature

Single height VME high speed counter board,XYCOM XVME series.

Dual AM9513A counter chip,support quadrature encoder decoding up to 5MHz.

Multi measurement modes:count,frequency,period,pulse width.

Built-in input hysteresis filter,suppress noise interference from field sensors.

Support hardware interrupt trigger at preset count value.

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:counter circuit damage or VME bus communication failure;

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

Encoder position reading abnormal:check A/B phase wiring,shield grounding and signal amplitude;

Counting loss:check input signal frequency exceed module 5MHz limit.

Product Brief

XYCOM XVME-203 is legacy VMEbus high speed counter and quadrature encoder module.

It collects pulse and encoder signals for position and speed measurement in VME control rack,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
