Features:
- Controller and HMI functions share the same SINUMERIK 828D PPU 280.3 hardware assembly.
- A 10.4-inch TFT color display provides 800 x 600-pixel operator visualization.
- The closed front reaches IP65 while the rear remains an IP20, UL open-type section.
Siemens 6FC5370-8AA30-0AA1 identifies the PPU 280.3 vertical variant within the SINUMERIK 828D hardware family.
The front operating area is limited to 0 to 45 deg C, while the rear section can operate from 0 to 55 deg C.
Its power-failure buffer is specified at 3 ms and extends to 20 ms when paired with the documented SITOP smart supply.
The Siemens 6FC5370-8AA30-0AA1 SINUMERIK 828D PPU 280.3 CNC Control may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
