Product Description:

The PPC-P11.1N-N-P1-NN-NN-FW is a control unit manufactured by Bosch Rexroth Indramat for the PPC Controllers series. Classified under internal series number 11 and released as design version 1, this board is delivered in an industrial PC housing so it can operate as the central motion processor inside compact machine controllers. It executes positioning loops and sequences, sending coordinated commands to servo drives and collecting status data from distributed I/O without the need for an external supervisory computer.

Communication is centered on a Profibus Master interface made available by the DPM01 card and routed through a 9-pin D-sub connector. The controller sustains transfer rates up to 12 MBaud, and cyclic data exchange can carry 7 Kbytes total per bus scan. Two RS-232/RS-485 ports, accessible through a 15-pin D-sub female connector, support local terminals or PLC links. Because memory expansion is not installed, all user code runs from internal flash. The digital output path can change state within 400 µs, which lets, the watchdog logic interrupt processes quickly, and each relay can switch up to 150 mA.

Installation follows the PCI Short Card format. Once seated, the backplane supplies three rails, with the heaviest draw on 3.3 V/1400 mA while the +5 V line is limited to 450 mA and the +12 V line carries no load. Input circuitry treats signals below the logic-low ceiling of 5 V as off and accepts highs from 15 V up to 30 V. Aggregate sinking capacity across the discrete outputs is 0.5 A. The watchdog relay contact tolerates 24 V, allowing direct wiring to drive enable loops. Mechanical retention is provided by the front bracket, and the unexpanded DPM01 board maintains bus timing and diagnostics continuously.
