Technical SpecificationsModel:0-51818-1 Brand:RELIANCE Product type:BCCB Binary Counter Conversion Board Weight:0.62kg Dimension:210mm138mm30mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE
System compatibility0-51818-1 belongs to RELIANCE BCCB binary counter conversion rack card. It is plug-in board for Reliance MaxPak series legacy DC drive rack,cooperates with main regulator board and pulse/encoder feedback circuit. It converts pulse frequency signals into binary digital value for speed monitoring and closed-loop processing. Commonly used for maintenance and spare replacement of old industrial DC drive equipment.
Function0-51818-1 is dedicated BCCB binary counter conversion PCB for RELIANCE MaxPak DC drive system. Receive pulse signals from tachometer generator or encoder. Complete pulse counting and frequency-to-binary digital conversion. Transmit converted binary speed value to drive main control regulator. Provide digital speed readout signal for front panel indication. Detect pulse signal loss and trigger fault warning. Onboard circuit filters noise pulse interference to avoid miscounting. Realize speed value latching for stable speed feedback.
InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-51818-1 BCCB board into drive rack slot and lock retaining screw. Connect gold finger backplane connector for internal signal exchange. Separate pulse feedback wiring from high-current power bus. Power on system,verify pulse counting and binary conversion accuracy. Check speed indication consistency with actual motor speed.
InterfaceBackplane edge connector,tachometer/encoder pulse input,binary data output,auxiliary power terminal,shield grounding terminal,status LED indicators.
FeatureRELIANCE 0-51818-1 rack plug-in BCCB binary counter conversion board. Discrete digital logic circuit for pulse counting and binary conversion. Built-in noise filter to suppress interference on tachometer signal. Gold plated edge connector for reliable rack contact. Front terminal strip for field pulse signal wiring. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old Reliance MaxPak DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation and maintenance.
DiagnosticMotor speed display incorrect:pulse signal attenuation or counter circuit failure; Speed reading jitter:noise interference on tachometer wiring; No binary output:missing auxiliary power; Speed loss alarm triggered:tachometer signal missing; Intermittent counting error:backplane pin oxidation and poor contact.
Product BriefRELIANCE 0-51818-1 is BCCB binary counter conversion board. It acquires tachometer/encoder pulse signals,performs pulse counting and binary conversion for Reliance MaxPak legacy DC drive speed feedback,widely used as spare part for legacy DC drive equipment maintenance.
