System compatibility

518315 belongs to RELIANCE CardPak series gate pulse trigger board.

Installed into CardPak DC drive rack,works with 490051 armature control board,490054 field regulator board and 518292 LVTC voltage control board.

Receive weak control pulse signal from regulator boards,amplify and distribute gate trigger pulses to SCR power thyristors.

Compatible with AutoMax control system for heavy industry production line.

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

Function

518315 is dedicated SCR gate pulse amplifier board for RELIANCE CardPak DC drive system.

Receive low-level pulse command from main regulator control board.

Amplify pulse power and distribute isolated trigger signal to each SCR thyristor in power stack.

Built-in pulse shaping and phase synchronization circuit to guarantee SCR reliable firing.

Detect pulse loss fault and send alarm signal to upper control board.

Onboard test points for pulse waveform measurement and phase debugging.

Provide isolation between low voltage control circuit and high voltage SCR power section.

Installation

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

Insert 518315 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane signal connector and SCR gate trigger wiring.

Trigger cables should be separated from low voltage analog signal cables.

Power on system,check pulse phase sequence and firing waveform.

Test SCR triggering performance and pulse loss protection function.

Interface

CardPak backplane edge connector,SCR gate trigger output terminal,pulse input port,test measurement points,status LED indicators.

Feature

RELIANCE 518315,CardPak SCR gate pulse trigger printed circuit board.

Pulse power amplification and multi-channel phase distribution for thyristor stack.

Electrical isolation between control side and high voltage power side.

Hardware pulse loss detection and fault alarm function.

Multiple test points for waveform inspection during on-site commissioning.

Standard CardPak plug-in structure,easy replacement together with 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 fire:pulse amplitude insufficient or trigger wiring loose;

Phase imbalance:pulse phase drift or board component aging;

Pulse loss alarm:pulse generation circuit damage;

LED abnormal:board auxiliary power supply failure;

Drive output jitter:pulse waveform distortion.

Product Brief
