System compatibility

0-51851 belongs to RELIANCE Cardpak series CRCA regulator board.

Designed for Reliance legacy Cardpak DC drive rack.

Work cooperatively with 0-48673 regulator board,0-49025 main control board.

Used in DC motor closed-loop speed control system for heavy industry equipment.

Commonly used for old drive equipment maintenance and spare replacement.

Function

0-51851 is parameter setting regulator card for RELIANCE Cardpak DC drive.

Front panel rotary dials set min speed,max speed,current limit and acceleration rate.

Convert manual dial setting into analog reference signal and send to main control loop.

Implement current limiting protection and acceleration ramp control for DC drive.

Coordinate with speed loop regulator to restrict operating range of motor.

Suppress sudden current impact during motor start and load variation.

Installation

Power off the whole drive cabinet and cut main power supply.

Insert 0-51851 board into designated Cardpak slot.

Fasten front panel fixing screws.

Connect edge connector and internal signal wiring.

Set four rotary dials according to motor and process requirement.

Power on system,run no-load test and verify limit parameters.

Check motor start ramp,speed range and current limiting performance.

Interface

Cardpak edge connector,front panel rotary adjustment dials,internal signal terminals.

Feature

RELIANCE 0-51851,CRCA parameter regulator PCB assembly for Cardpak drive.

Front panel 4 rotary dials for onsite quick parameter configuration.

Onboard precision potentiometer matched with each dial.

Clear grid coordinate marking on PCB for convenient maintenance.

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

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

Diagnostic

Motor cannot reach set max speed:check max speed dial setting or board circuit;

Motor overcurrent alarm frequently:current limit value set too high or board failure;

Slow acceleration response:accel rate dial parameter improper;

No parameter signal output:edge connector poor contact or component aging.

Product Brief

RELIANCE 0-51851 is CRCA regulator control circuit board.
