Technical SpecificationsModel:0-52002-3 Brand:RELIANCE Product type:S2 Relay Board Weight:0.51kg Dimension:210mm135mm30mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-52002-3 is RELIANCE S2 rack plug-in relay board. It is designed for Reliance MaxPak Plus series spindle DC drive rack,cooperates with IOB input output board and SSC static sequence board. It uses onboard relays to convert internal drive logic signals into dry contact outputs for external interlock,alarm and status indication. Commonly used for maintenance and spare replacement of old industrial spindle DC drive equipment.

Function0-52002-3 is dedicated S2 relay PCB for RELIANCE MaxPak Plus DC drive system. Receive internal logic signals such as drive ready,fault,overload and speed reach from control rack. Equipped with 5 onboard relays,providing isolated dry contact outputs for external PLC or auxiliary control circuit. Screw terminal block for field wiring connection. Multi-channel LED indicators display each relay actuation status. Built-in coil surge absorption circuit to suppress back EMF and protect backplane logic circuit.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-52002-3 S2 relay board into drive rack slot and lock retaining screw. Connect gold finger backplane connector for internal logic signal exchange. Separate relay contact field wiring from analog feedback and pulse cables. Power on system,test relay pull-in action by triggering drive status conditions. Verify contact switching continuity.

InterfaceBackplane edge connector,internal logic signal input,dry relay contact output,screw terminal block,auxiliary power terminal,shield grounding terminal,multi-channel relay status LED indicators.

FeatureRELIANCE 0-52002-3 rack mount S2 relay board. 5 built-in relays with dry contact output for drive status signals. Onboard surge suppression for relay coils. Gold plated edge connector for reliable rack signal transmission. Multi LED visual indication for each relay working state. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old Reliance MaxPak Plus DC drive system spare replacement. Suitable for metallurgy,paper-making production line spindle DC drive renovation and maintenance.

DiagnosticRelay no pull-in:logic input missing or relay coil burnout; Contact cannot switch:relay contact aging and oxidation; LED no response:board auxiliary power loss; Random false alarm:interference trigger; Intermittent signal loss:backplane pin oxidation and poor contact.

Product BriefRELIANCE 0-52002-3 is S2 relay board. It receives internal status signals from Reliance MaxPak Plus legacy spindle DC drive and outputs isolated dry relay contacts for fault,ready and interlock signal transmission to external control equipment,widely used as spare part for legacy DC drive equipment maintenance.
