Features:
- Combines SINUMERIK 840D sl CNC processing with PLC 317-3 PN/DP logic.
- Provides 2 GB DRAM and manufacturer-defined non-volatile storage.
- Uses a 24 V DC, twin-fan hardware configuration for machine control.
The complete order code identifies the NCU 730.3B PN spare configuration with integrated PLC and twin cooling fans.
It closes the control loop between CNC interpolation, machine sequencing and connected drives or I/O.
Match software, CompactFlash, licenses, topology and backup sets before selecting or installing another NCU.
This spare-only NCU is supplied after machine configuration and license compatibility are confirmed.
