Technical SpecificationsModel:0-51381-16 Brand:RELIANCE Product type:Flexpak Controller Board Weight:0.81kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-51381-16 belongs to RELIANCE Flexpak series main controller board. Installed inside Flexpak DC variable speed drive cabinet,cooperates with pulse trigger circuit and SCR rectifier stack. It executes full analog double closed-loop control for Flexpak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function0-51381-16 is dedicated main analog control PCB for RELIANCE Flexpak DC drive system. Receive external speed reference signal and tachometer speed feedback. Complete speed PI regulation and current closed-loop calculation. Output firing angle command to pulse generation circuit. Integrate multi fault detection logic including overcurrent,loss of tacho,overvoltage. Provide run/stop interlock and fault latch protection. Built-in acceleration/deceleration ramp generator and adjustable current limit function.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-51381-16 board into designated chassis slot and lock retaining fasteners. Connect backplane connector and field analog & logic wiring. Separate low voltage signal wiring from high-current power bus. Power on system,tune speed loop gain and current limit potentiometer. Verify start,stop and variable load running performance.

InterfaceBackplane bus connector,speed reference input,tachometer feedback input,firing command output,fault logic output,adjustment potentiometer,status LED indicators.

FeatureRELIANCE 0-51381-16,plug-in analog main control board for Flexpak DC drive. Speed and current double closed-loop analog control circuit. Integrated ramp generator and multi-condition fault latch circuit. Onboard potentiometers for loop gain and current limit tuning. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old Flexpak DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation and maintenance.

DiagnosticMotor speed unstable:tacho signal interference or loop gain improper; Drive cannot start:enable interlock lockout or reference missing; Frequent overcurrent trip:current limit potentiometer misadjustment; No firing pulse command output:internal analog circuit damage; Intermittent drive shutdown:backplane connector poor contact.

Product BriefRELIANCE 0-51381-16 is Flexpak controller board. It completes analog double closed-loop speed & current regulation,firing angle calculation and multi fault protection for Reliance Flexpak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
