DELEM 7440-301/C Rack Backplane Board

Technical SpecificationsModel: 7440-301/C Brand: DELEM (Netherlands) Product Type: Modusys Backplane Board Mounting: Installed inside electrical cabinet rack Operating temperature: 0℃ ~ +45℃ Storage temperature: -20℃ ~ +70℃ Relative humidity: 5%~95%, non-condensing Protection: IP00 (bare circuit board) Power supply: 24V DC Weight: 0.72 kg

System compatibility7440-301/C is DELEM classic Modusys rack backplane board. It is the signal distribution base for DM series axis modules including DM01,DM04,DM102,DM104. It connects HSB bus, 24V power supply and signal lines between DA controller and axis modules, widely used for legacy electro-hydraulic synchronous press brake maintenance.

Function7440-301/C provides HSB high-speed bus routing and power distribution for multiple DM axis modules mounted on the rack. It transmits communication signals, encoder feedback signals and analog valve control signals between the main CNC controller and each axis module. It integrates power distribution terminals and signal filtering circuits, monitors bus power state. It is used to replace defective backplane when the whole Modusys system suffers intermittent communication failure.

InstallationCut off main power supply before installation. Mount 7440-301/C inside the electrical cabinet rack, install DM modules onto the backplane connectors. Connect 24V DC input, HSB bus cable and ground wire. Check all connector tightness, verify signal continuity before powering on and loading machine parameters.

InterfaceHSB bus connector, module slot connectors, 24V DC power terminals, ground terminal, signal distribution terminals for DELEM 7440-301/C backplane board.

FeatureOriginal DELEM Modusys backplane board, multi-module bus expansion, built-in signal filtering, stable power distribution, standard rack layout. This legacy spare part supports field repair of old DELEM electro-hydraulic press brake systems.

DiagnosticNo power on modules: check 24V DC power input and fuse for 7440-301/C. Intermittent HSB bus errors: inspect backplane connectors, pin oxidation and cabinet grounding. Multiple axis modules offline: check backplane bus wiring and power distribution circuit.

Product Brief7440-301/C is Dutch DELEM Modusys rack backplane board for press brake axis modules. It realizes HSB bus signal transmission and power distribution for DM series motion control modules, classic spare part for legacy metal fabrication machine overhaul.
