Product Description:
The PPC-P01.1A-N-NN-NN-NN-FW control unit is produced by Bosch Rexroth Indramat within the PPC Controllers series. As a dedicated automation controller, it supervises motion sequences and peripheral tasks by exchanging data with drives and field devices over real-time networks. Installed inside machine control cabinets, the module provides the central processing and memory resources required to coordinate servo axes and I/O points in industrial production lines.
At the heart of the board is a PowerPC microprocessor that uses 8 MB SDRAM of main memory and accesses an additional 4 MB SDRAM segment reserved for buffered process data. A soldered 256-byte serial EEPROM stores persistent parameters, while a plug-in 4 MB expansion module allows program growth. The electronics draw up to 1.5 A from the regulated backplane supply at 5 VDC, so cabinet power budgeting must account for this peak current. To link motion drives, the controller carries a SERCON 816 Sercos chipset and exposes a PC/104 stack connector for fieldbus or I/O extensions, allowing the unit to process cyclic setpoint traffic without overloading the central bus.
The card shares status information through a RS232 diagnostic port and a Mini-DIN 8-pin service socket that support firmware loading and live trace functions. Host communication with the PLC rack is handled by an ISA edge connector, and further hardware layers can slide onto the PC/104 header without increasing the overall footprint. The unit has a width of 293 mm, a height of 142 mm, and a compact depth of 23 mm, which supports straightforward DIN rail insertion. Despite the board area, the assembly weighs only 240 g, and a Renata CR2477N lithium cell maintains real-time clock data during power loss while the design version 1 housing protects the electronics from debris encountered in automated machinery.
