Technical SpecificationsModel:0-49061 Brand:RELIANCE Product type:Speed Regulator Card Weight:0.76kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-49061 belongs to RELIANCE CardPak series speed regulator card. Installed into CardPak rack,works with current reference card and speed feedback board. It implements closed speed loop regulation for CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function0-49061 is dedicated speed loop regulator board for RELIANCE CardPak DC drive system. Receive speed reference signal and actual speed feedback signal. Calculate speed deviation and output error signal to current reference card. Built-in PI adjustment for speed loop stability. Adjust response gain to suppress speed fluctuation under load variation. Provide speed saturation limiting function. Generate speed error signal for upper control logic.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-49061 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and analog speed signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,calibrate speed loop gain and integral parameter. Verify speed stability under no-load and variable load condition.

InterfaceBackplane bus connector,speed reference input,speed feedback input,speed error analog output,adjustment potentiometer,status LED indicators.

FeatureRELIANCE 0-49061,CardPak rack mount speed regulator card. Analog PI speed closed-loop control circuit. Adjustable gain and integral time for loop tuning. Low drift analog signal processing circuit. Speed saturation limit to avoid overshoot. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old CardPak DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation and maintenance.

DiagnosticMotor speed unstable:loop gain improper or feedback signal noise; Cannot reach set speed:speed reference loss or integral circuit fault; Speed overshoot during start-up:gain setting too high; Speed drift with temperature:internal analog component aging; Drive no speed response:backplane connector poor contact.

Product BriefRELIANCE 0-49061 is CardPak speed regulator card. It completes speed closed-loop calculation and outputs error signal to current loop for Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
