System compatibility

0-55325-24 belongs to RELIANCE CardPak series base driver board.

Installed into CardPak DC drive rack,works with 5138116 main controller board,5186518 current loop driver board,563052 auxiliary power supply board and other plug-in regulator boards.

Responsible for SCR thyristor gate pulse amplification and trigger driving of DC drive power unit.

Compatible with AutoMax control system for heavy industry production line.

Commonly used for old DC drive equipment maintenance and spare replacement.

Function

0-55325-24 is dedicated SCR base driver PCB board for RELIANCE CardPak DC drive system.

Receive low-level firing angle control signal from current loop regulator board.

Amplify control signal into strong gate trigger pulse to drive power SCR thyristor.

Synchronize pulse phase with main AC power supply to ensure stable rectifier operation.

Built-in pulse monitoring circuit to detect missing trigger pulse fault.

Output fault alarm signal to interface logic board when pulse abnormality occurs.

Onboard test points for pulse waveform inspection during commissioning and troubleshooting.

Installation

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

Insert 0-55325-24 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane edge connector and SCR gate wiring.

High-power trigger wiring must be separated from low voltage analog signal cable.

Power on system,check pulse phase synchronization and trigger waveform.

Test pulse loss detection and fault alarm function.

Interface

CardPak backplane edge connector,low level control signal input terminal,SCR gate pulse output port,pulse monitoring test points,status and fault LED indicators.

Feature

RELIANCE 0-55325-24,CardPak SCR base drive printed circuit board.

Convert weak analog control signal into high-energy SCR trigger pulse.

AC line synchronization design to stabilize rectifier firing angle.

Pulse loss fault detection for power unit protection.

Multiple test points for onsite waveform measurement.

Standard CardPak plug-in structure,easy replacement together with other regulator boards.

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

SCR cannot trigger:no pulse output or gate wiring open circuit;

Drive jitter:trigger pulse amplitude insufficient or phase desynchronization;

Pulse loss alarm:drive circuit component aging;

Unbalanced three-phase rectification:one channel pulse circuit damaged;

LED no lighting:board auxiliary power supply failure.

Product Brief

RELIANCE 0-55325-24 is CardPak base driver board.
