Technical Specifications Model:0-49008-A Brand:RELIANCE Product type:Limit Module Board Weight:0.93kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility 0-49008-A belongs to RELIANCE CardPak series limit module board. Installed into CardPak rack,works with regulator board and power supply board. It implements speed and current over-limit protection logic for CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function 0-49008-A is dedicated limit protection module board for RELIANCE CardPak DC drive system. Monitor motor speed and loop current real-time signal. Set threshold via onboard potentiometer for over-speed and over-current limit. Trigger signal cut-off and alarm output when measured value exceeds preset limit. Latch fault state and send fault signal to main regulator card. Provide reset function after fault elimination. Prevent motor and power unit damage caused by abnormal operating conditions.

Installation Power off the whole drive cabinet and cut main power supply. Insert 0-49008-A board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and analog monitoring signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,adjust front potentiometer to set limit threshold. Test protection trigger and reset function.

Interface Backplane bus connector,analog signal input terminal,fault output terminal,adjustment potentiometers,status & fault LED indicators.

Feature RELIANCE 0-49008-A,CardPak rack mount limit protection board. Dual over-speed and over-current limit monitoring. Onboard potentiometer for on-site threshold adjustment. Fault latch function to retain alarm record. 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.

Diagnostic Drive trips frequently:limit threshold set too low or signal interference; No protection action:monitoring circuit failure or potentiometer drift; Fault LED keeps lit:latch state not reset after fault removal; Random false alarm:signal wiring loose or noise interference; Regulator board no fault report:backplane communication abnormal.

Product Brief RELIANCE 0-49008-A is CardPak limit module board. It provides over-speed and over-current limit protection for Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
