DELEM DAC250 NC Shearing Machine Controller

Technical Specifications

Model: DAC250 Brand: DELEM (Netherlands) Product Type: NC Controller for Hydraulic Shearing Machine Mounting: Panel mounting on shear machine cabinet Operating temperature: 0℃ ~ +45℃ Storage temperature: -20℃ ~ +70℃ Relative humidity: 5%~95%, non-condensing Protection: IP20 (front panel) Power supply: 24V DC Weight: 2.5 kg

System compatibility

DAC250 is an economical compact single-axis NC controller for hydraulic guillotine shearing machines. It matches incremental encoder and digital I/O modules, supports DC motor, two-speed AC motor and inverter drive for backgauge, widely used in metal fabrication workshops for controller replacement during legacy sheet metal shear overhaul.

Function

DAC250 serves as the core backgauge positioning control unit of hydraulic shearing machine. It supports multi-step cutting position programming, controls single X axis backgauge closed-loop positioning and retract function, counts finished workpieces. It has backlash compensation function and automatic reference point search, keeps zero position accuracy after power cycle. It monitors axis travel limit and signal state, triggers alarm signals once over-travel or signal faults are detected. It is used to replace damaged controllers when the guillotine shear cannot complete backgauge positioning programming.

Installation

Cut off main power supply before installation. Reserve panel cutout on machine cabinet, mount DAC250 and lock fixing fasteners. Connect 24V DC power, encoder cables and digital I/O terminals. Check wiring definition, upload machine parameters, perform trial cutting test before formal production.

Interface

Encoder input port, digital I/O terminals, analog speed output, status LED digital display for DELEM DAC250 controller.

Feature

Original DELEM compact NC controller, dual red LED digital display, membrane numeric keypad, simple multi-step position programming, built-in self-diagnostic function, power-off position memory, compact thin panel housing, low power consumption. This legacy spare part supports field repair of old hydraulic guillotine shear systems.

Diagnostic

No display after power on: check 24V DC power supply and power fuse for DAC250. Backgauge positioning error: verify encoder wiring polarity and machine parameter setting. Intermittent positioning jump: inspect encoder cable shielding and cabinet grounding condition.

Product Brief

DAC250 is Dutch DELEM compact NC controller for hydraulic guillotine shearing machine. It executes single-axis backgauge positioning and multi-step position programming for sheet metal shearing operation, classic spare part for legacy metal fabrication machine overhaul.
