RELIANCE 0-49029-2 Instantaneous Electronic Trip Module

Technical SpecificationsModel:0-49029-2 Brand:RELIANCE Product type:Instantaneous Electronic Trip Module Weight:1.08kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-49029-2 belongs to RELIANCE CardPak series instantaneous electronic trip module. Installed into CardPak rack,works with current feedback board and driver board. It provides fast overcurrent protection for CardPak DC drive power unit. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function0-49029-2 is dedicated instantaneous overcurrent trip protection board for RELIANCE CardPak DC drive system. Continuously monitor DC loop current signal from feedback board. Trigger instantaneous trip signal once current exceeds preset threshold. Cut off SCR firing pulse to protect thyristor and motor. Equipped with manual reset button for fault reset after trip. Hold fault latch status until manual reset operation. Prevent severe damage caused by short-circuit and sudden heavy overload.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-49029-2 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and current monitoring signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,set trip current threshold according to motor rating. Test trip and reset function to verify protection response.

InterfaceBackplane bus connector,current signal input,trip logic output terminal,manual reset button,status LED indicators.

FeatureRELIANCE 0-49029-2,CardPak rack mount instantaneous electronic trip module. Ultra fast response overcurrent protection circuit. Latching fault status with local manual reset button. Adjustable trip threshold for different motor specifications. Hardware level protection independent of main control loop. 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.

DiagnosticFalse trip during normal operation:trip threshold set too low or signal noise; No trip under short-circuit condition:protection circuit failure; Cannot reset after trip:latch circuit or reset button damage; Trip LED not lit:board power supply fault; Random protection action:backplane connector poor contact.

Product BriefRELIANCE 0-49029-2 is CardPak instantaneous electronic trip module. It offers fast overcurrent and short-circuit protection for Reliance CardPak DC drive unit,widely used as spare part for legacy DC drive equipment maintenance.
