Technical SpecificationsModel:0-49060-1 Brand:RELIANCE Product type:Current Reference Card Weight:0.75kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-49060-1 belongs to RELIANCE CardPak series current reference card. Installed into CardPak rack,works with summing board and current feedback board. It generates analog current setpoint signal for CardPak DC drive current loop control. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function0-49060-1 is dedicated current reference control board for RELIANCE CardPak DC drive system. Generate adjustable analog current command signal for current regulator. Accept speed loop output signal and convert to current reference value. Limit maximum current setpoint to protect motor and power stack. Cooperate with current feedback board to form closed current loop. Provide current ramp function for smooth current build-up. Output stable low-drift analog reference signal to subsequent control boards.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-49060-1 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and analog signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,calibrate maximum current limit and ramp rate. Verify current reference response during drive start and load change.

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

FeatureRELIANCE 0-49060-1,CardPak rack mount current reference card. Precision analog current setpoint generation. Adjustable maximum current limiting protection. Built-in current ramp circuit to avoid current shock. Low temperature drift analog circuit for stable reference output. 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 current cannot rise:current reference signal missing; Overcurrent alarm frequently triggered:current limit setting too high; Slow current response:ramp parameter mis-calibration; Current value drift during operation:internal reference component aging; No current command output:backplane connector poor contact or board power failure.

Product BriefRELIANCE 0-49060-1 is CardPak current reference card. It produces current setpoint signal and current limiting function for current closed-loop control of Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
