System compatibility

0-51381-16 belongs to RELIANCE CardPak series main controller board.

Installed into CardPak DC drive rack,works with 490054 field regulator board,563052 auxiliary power supply board,518317 interface control board and other plug-in boards.

Serve as the core control card for analog DC drive closed-loop regulation.

Compatible with AutoMax control system for heavy industry production line.

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

Function

0-51381-16 is dedicated main regulator control PCB board for RELIANCE CardPak DC drive system.

Complete speed loop and current loop double closed-loop calculation of DC motor.

Four onboard adjustable potentiometers:IR COMP,current limit,max speed,accelerate setting.

Receive speed reference signal and feedback signal from tachometer,current sampling board.

Output control command to pulse amplifier board to adjust SCR firing angle.

Built-in signal limiting and compensation circuit to optimize motor dynamic response.

Onboard test points for loop signal measurement and parameter calibration.

Installation

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

Insert 0-51381-16 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane edge connector and signal wiring.

Analog signal wiring adopt shielded cable and separate from high voltage power cable.

Power on system,adjust four potentiometers to set drive parameters.

Test speed regulation stability and current limiting protection function.

Interface

CardPak backplane edge connector,analog reference & feedback terminal,pulse command output port,adjust potentiometers,test measurement points,status LED indicators.

Feature

RELIANCE 0-51381-16,CardPak core main regulator printed circuit board.

Double closed-loop control of speed and current for DC drive.

Front panel multi-turn potentiometer for direct onsite parameter setting.

IR compensation circuit reduces speed drop under heavy load condition.

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

Speed unstable:tach signal abnormal or IR COMP potentiometer drift;

Cannot reach max speed:max speed potentiometer misadjustment;

Current limiting ineffective:current limit potentiometer failure;

No pulse command output:backplane connector poor contact or board power fault;

LED no lighting:board auxiliary power supply failure.

Product Brief

RELIANCE 0-51381-16 is CardPak main controller board.

It implements speed and current double closed-loop control for Reliance legacy DC drive,with onboard potentiometers for parameter setting,widely used as spare part for heavy industry DC drive system maintenance.
