System compatibility

490051 belongs to RELIANCE CardPak series drive control board.

Installed into CardPak drive rack,matched with Reliance legacy DC drive power unit.

Can work together with other CardPak series regulator boards to realize full closed-loop DC motor speed control.

Compatible with AutoMax control system for heavy industry production line.

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

Function

490051 is dedicated control PCB board for RELIANCE CardPak DC drive system.

Complete speed loop and current loop closed-loop operation for DC motor.

Receive analog setpoint signal from upper controller,output gate trigger signal to SCR power module.

Collect armature voltage and current feedback signal for drive protection calculation.

Built-in overcurrent,overvoltage and overspeed detection logic.

Onboard test points for on-site signal measurement and parameter tuning.

Transmit drive fault signal to upper control system when abnormality occurs.

Installation

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

Insert 490051 board into designated slot of drive rack.

Fasten fixing screws.

Connect backplane signal connector and feedback wiring.

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

Power on system,calibrate current and speed loop parameters.

Test motor speed regulation and protection function.

Interface

CardPak backplane edge connector,analog feedback terminal,SCR trigger output port,test measurement points,status LED indicators.

Feature

RELIANCE 490051,CardPak DC drive control printed circuit board.

Integrated analog closed-loop regulation circuit for armature control.

Multiple test points for convenient maintenance debugging.

Hardware protection circuit to avoid motor and power unit damage.

Standard CardPak plug-in structure,easy replacement.

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

Motor speed unstable:loop parameter drift or feedback wiring interference;

No trigger output:backplane connector loose or board power fault;

Overcurrent alarm:current sampling circuit damage or motor winding fault;

LED abnormal:board power supply failure;

Drive cannot run:interlock protection triggered.

Product Brief

RELIANCE 490051 is CardPak DC drive control board.

It executes speed and current closed-loop regulation and outputs trigger signal for SCR power unit,widely used as spare part for heavy industry DC drive system maintenance.
