System compatibility

0-518292 belongs to RELIANCE CardPak series LVTC linear voltage control board.

Installed into CardPak DC drive rack,matched with 490051 armature control board and 490054 field regulator board.

Used for armature voltage sampling and linear closed-loop control of large Reliance DC drives.

Compatible with AutoMax control system for heavy industry production line.

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

Function

0-518292 is dedicated LVTC linear voltage control PCB board for RELIANCE CardPak DC drive system.

Sample DC motor armature voltage signal and realize linear voltage closed-loop regulation.

Convert voltage feedback signal into standard analog signal and transmit to main control board.

Built-in voltage scaling and offset adjustment circuit for onsite calibration.

Hardware overvoltage detection circuit to trigger drive protection.

Onboard multiple test points for armature voltage measurement and loop tuning.

Detect voltage feedback loss and output fault alarm signal.

Installation

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

Insert 0-518292 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane edge connector and armature voltage feedback wiring.

High voltage feedback wiring should be separated from low voltage signal cable.

Power on system,adjust offset and gain potentiometer for voltage calibration.

Test armature voltage closed-loop response and overvoltage protection.

Interface

CardPak backplane edge connector,armature voltage high voltage feedback terminal,analog output port,test measurement points,status LED indicators.

Feature

RELIANCE 0-518292,CardPak LVTC linear voltage control printed circuit board.

Specialized for armature voltage closed-loop sampling and regulation.

Potentiometer gain and offset adjustment for flexible onsite calibration.

Hardware overvoltage protection to protect motor and SCR power unit.

Standard CardPak plug-in structure,easy replacement and maintenance.

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

Armature voltage drift:potentiometer parameter drift or feedback wiring interference;

No voltage feedback signal:high voltage terminal loose or sampling circuit damage;

Overvoltage false alarm:sampling scaling incorrect;

LED abnormal:board auxiliary power supply failure;

Drive shutdown:voltage feedback loss protection triggered.

Product Brief

RELIANCE 0-518292 is CardPak LVTC linear voltage control board.
