Product Description:

The PPC-R22.1N-T-T3-P1-NN-FW is a control unit from the PPC Controllers series produced by Bosch Rexroth Indramat. Within an automation line, the device executes program code, exchanges real-time data with drives, and supervises I/O so that coordinated motion profiles and sequence logic remain synchronized. It is supplied in the RECO housing design for DIN-rail installation next to power electronics, and it links multiple communication networks in packaging, printing, and material-handling machines. This arrangement places control functions near the associated drive hardware inside the cabinet.

The unit operates from a 24 VDC supply and draws up to 1.2 A under load. The enclosure has an IP20 rating, so the module must be installed in a clean, closed cabinet. Integrated fieldbus hardware includes a 100 Mb EtherNet interface labeled ETH02 and a Profibus port that operates at up to 12 MBaud. Two optically isolated serial ports start at 9600 baud and can be set to higher rates for diagnostics, while a Sercos fiber link synchronizes servo drives. This combination lets the controller exchange plant-level data while maintaining deterministic motion communication on the drive network. Ripple on the logic rail remains below 4 Vpp, which helps keep communication stable.

The controller provides 3 expansion slots for optional I/O or additional bus cards. The backplane supports Sercos communication up to 16 MBaud without overrun, and the serial port can be set as high as 115200 baud when faster diagnostic transfers are needed. The carrier accepts field wiring up to 1.5 mm², and the total unit mass of 1.3 kg keeps DIN-rail loading modest during vibration. The compact mass also helps reduce rail stress when the cabinet is exposed to shock or repeated machine movement. The unit is version 1, and the four-digit LED display provides concise status codes because no separate memory expansion is installed.
