Product Details

The Delem DAC-250 is an early classic single-axis programmable NC controller dedicated to backgauge positioning for hydraulic guillotine shears. This shear backgauge NC controller relies on incremental encoder feedback to deliver stable length positioning for sheet cutting jobs. As a reliable guillotine shear positioning unit, it supports servo, single-speed and two-speed drive systems and adopts a simple numeric membrane keypad for straightforward operation. This sheet metal shear NC unit is widely used as a direct replacement spare part for ageing small and medium shearing machines, offering dependable cut-length accuracy and low maintenance demand for sheet metal fabrication workshops.

Supported Functions

This shear backgauge NC controller supports manual jog movement, single cutting cycle and sequential automatic cutting. The guillotine shear positioning unit provides backgauge retract function, position preset, batch counter and inch / metric unit switching. It supports absolute and incremental positioning adjustment, travel limit setting and basic parameter calibration. This sheet metal shear NC unit also comes with built-in I/O testing and clear alarm indication for fast on-site debugging.

Core Functions

Precision encoder counting ensures repeatable backgauge positioning for batch cutting production. The shear backgauge NC controller executes preset positioning sequences accurately and retains stored cutting programs after power loss. It outputs interlock and drive signals to coordinate the shear machine cycle. Integrated fault detection helps technicians quickly locate encoder, wiring and signal faults to reduce machine downtime. Its compact panel mounting design allows easy swap for the original failed controller on old shearing equipment.
