Product Details

The Delem 7441-002/1 is an original OEM CNC control circuit board designed for Delem press brake and shearing machine numerical control systems. This CNC control circuit board undertakes critical signal conditioning, encoder feedback reception and internal bus communication between the Delem main controller and drive peripherals. As a reliable press brake signal board, it adopts dedicated pin layout matching Delem backplane sockets, supporting stable transmission of axis feedback signals for Y1, Y2, X, R, Z1 and Z2. This Delem spare board is widely stocked as an original replacement spare part for repairing and upgrading legacy Delem CNC systems, restoring normal bending and shearing functions for sheet metal machine tools.

Supported Functions

This CNC control circuit board supports acquisition and preprocessing of incremental encoder feedback signals for all controlled axes. The press brake signal board realizes reliable signal exchange between the Delem main control unit, drive modules and I/O terminals. It provides hardware signal filtering to suppress electromagnetic interference inside workshop equipment. This Delem spare board supports hot-swap maintenance for qualified technicians and retains original system signal logic after replacement.

Core Functions

High-precision signal conditioning circuits clean up noisy encoder feedback to guarantee accurate axis positioning and synchronization. The CNC control circuit board forwards motion commands and position feedback data steadily over the internal system bus. It ensures synchronous operation of Y1 and Y2 ram axes and accurate positioning of backgauge axes. Onboard fault detection circuits feed back channel abnormality to the Delem HMI for fast diagnosis. Its original footprint enables direct plug-and-play substitution for the faulty original board without complicated wiring modification.
