System compatibility

XVME-293 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.

5 digital output channels for pulse or alarm signal output,with FOUT dedicated output.

Support hardware interrupt to notify CPU once count target reached.

Support signal routing via rear P2 backplane connector,suitable for rear wiring chassis.

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-293 card into empty VME slot,tighten front panel fixing screw.

Set base address and interrupt level via board jumpers.

Connect encoder/pulse signal either to front 50pin connector or rear P2 backplane.

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 front ribbon terminal,P2 96pin rear I/O connector,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.

5 output channels plus FOUT signal,more outputs than XVME-203.

Dual I/O routing option:front panel wiring or rear P2 backplane wiring.

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;

Count loss:confirm input pulse frequency does not exceed 5MHz limit;

Rear I/O no signal:check P2 backplane pin connection.

Product Brief

XYCOM XVME-293 is legacy VMEbus high speed counter and quadrature encoder module with rear P2 I/O.

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.
