Real-time collect analog signal from each regulator board test points.

Display speed reference,current feedback,voltage feedback,pulse waveform signal for drive commissioning.

Assist engineers to calibrate loop gain,offset and protection threshold of DC drive.

Simulate partial reference and interlock signal for offline board testing.

Quickly locate faulty CardPak plug-in board during drive failure.

Onboard multi-channel signal indicator and test sockets for instrument connection.

Installation

Power off the whole CardPak drive rack and cut main power supply.

Insert 0-49026-21 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane edge connector for internal signal acquisition.

Separate low voltage test signal cable and high voltage power cable.

Power on system,read each loop signal and perform calibration adjustment.

Simulate fault condition to verify drive protection response.

Interface

CardPak backplane edge connector,signal test socket,status indicator lamp,external instrument measurement port,test measurement points.

Feature

RELIANCE 0-49026-21,CardPak dedicated commissioning and diagnostic printed circuit board.

Integrated multi-channel signal acquisition for all regulator boards.

Support onsite loop calibration and offline single board inspection.

Visual signal indicator for fast fault judgement.

Standard CardPak plug-in structure,easy plug and test.

Discontinued obsolete board,supply only for old automation drive system spare replacement.

Suitable for metallurgy,paper-making heavy-duty DC drive production line renovation.

Diagnostic

No signal display:backplane connector poor contact or tester board power fault;

Signal reading deviation:test channel circuit component aging;

Indicator no lighting:board auxiliary power abnormal;

Cannot simulate reference signal:internal signal generation circuit damage;

Interlock test invalid:signal isolation circuit failure.
