System compatibility

70203-001 XVME-203 belongs to XYCOM XVME series VME I/O board.

It plugs into VME chassis and cooperates with XVME series CPU board.

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

Collect quadrature encoder pulse signals,realize position,velocity and rotation speed measurement.

High-speed pulse counting,phase discrimination to judge forward and reverse rotation.

Onboard hardware counter,reduce host CPU calculation load.

Upload position and speed data to VME host CPU for closed-loop motion control.

Onboard self-test circuit for channel and hardware fault inspection.

Installation

Power off VME chassis.

Insert 70203-001 XVME-203 card into empty 6U VME slot,tighten front panel fixing screw.

Connect encoder A/B/Z phase wiring to module terminal block.

Power on chassis,run VME system scan and self-test program.

Test each counting channel,calibrate encoder position reading.

Interface

VME P1/P2 backplane connector,field signal terminal block,LED indicators:RUN,COM,FAULT.

Feature

Single height 6U VME standard board,easy installation in VME rack.

Support quadrature encoder signal,high resolution position measurement.

Hardware counting circuit,strong anti-interference for industrial pulse signal.

Discontinued obsolete VME counter module,supply only for old production system spare replacement.

Vibration resistant PCB design,suitable for continuous long-time industrial operation.

Diagnostic

FAULT LED on:channel overvoltage or backplane poor contact;

No pulse counting:check encoder power and A/B phase wiring;

Direction identification error:check phase sequence wiring of encoder.

Product Brief

XYCOM 70203-001 XVME-203 is legacy 6U single height VMEbus quadrature counter module.

It acquires encoder pulse signals and calculates position and speed,widely used as spare part for turbine and compressor control,petrochemical and power plant old DCS renovation.
