Technical SpecificationsModel:0-51811-3 Brand:RELIANCE Product type:Voltmeter Tester Card (TSTB Board) Weight:0.40kg Dimension:180mm105mm40mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE
System compatibility0-51811-3 is upgraded revision of 0-51811-1 TSTB voltmeter tester card. It is VME-style plug-in module,used with Reliance legacy DC drive rack system. It serves as on-board test instrument for drive analog circuit measurement,commissioning calibration and troubleshooting. Commonly used for maintenance and spare replacement of old industrial DC drive equipment.
Function0-51811-3 is upgraded TSTB analog voltmeter tester PCB for RELIANCE DC drive system. Equipped with front panel analog DC voltmeter and expanded multi-range selector knobs. Tap internal analog test points of drive rack,measure control loop voltage signals including regulator error,reference and feedback voltage. Wider measurement range compared with earlier 0-51811-1 version. Real-time visual readout for on-site calibration of drive analog control boards. Assist technician to locate abnormal analog signals during fault diagnosis. Provide adjustable test signal access point for circuit verification.
InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-51811-3 TSTB card into drive rack slot and lock retaining screw. Connect backplane edge connector to access internal test signals. Separate low voltage measurement wiring from high-current power bus. Power on drive rack,rotate range knob and read voltmeter indication. Perform calibration adjustment of related control boards according measured value.
InterfaceBackplane edge connector,front panel range selector knobs,built-in analog DC voltmeter,test signal tap terminals,shield grounding terminal.
FeatureRELIANCE 0-51811-3 plug-in rack mount TSTB tester card. Integrated analog moving coil voltmeter and expanded multi-range switching circuit. Front panel mechanical knobs for measurement range selection. Improved noise suppression circuit for stable meter reading. Designed for direct insertion into Reliance drive backplane without external test meter. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old Reliance DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation and maintenance.
DiagnosticMeter pointer no deflection:backplane poor contact or internal circuit open; Reading deviation:meter aging or range potentiometer drift; Cannot switch measurement range:selector switch wear; Unstable pointer swing:signal interference or bad grounding; No access to test point:backplane pin corrosion.
Product BriefRELIANCE 0-51811-3 is upgraded TSTB voltmeter tester card. It is rack plug-in test module for Reliance legacy DC drive,used for analog control voltage measurement,on-site calibration and fault troubleshooting,widely used as spare part for legacy DC drive equipment maintenance.
