Product Description:

The PPC-R02.2N-N-Q1-L2-T2-FW is a control unit from the PPC Controllers series produced by Bosch Rexroth Indramat. Mounted in a RECO housing, the unit serves as the central processing and communication element in distributed automation where coordinated motion, data acquisition, and networked I/O are required. Within a multi-axis drive or machine line, it interprets program logic, exchanges status over fieldbus links, and supervises local digital I/O so that actuators and sensors operate in a deterministic sequence. This arrangement lets one compact module handle both control tasks and communication inside a rack-based system.

The controller is powered from a nominal 24 VDC supply and draws up to 52 W from the backplane I/O bus to feed its logic circuitry and attached modules. Three digital inputs and two digital outputs allow direct connection of limit switches or interlocks, while 2.3 A and 3.0 A rails on the 24 V and 5 V buses support additional cards inserted beside it. Network access is provided through a 10 Mb Ethernet interface for supervisory traffic and a ControlNet fieldbus slave interface for real-time control frames. Under peak computation load, the device draws no more than 1.2 A from the cabinet supply, which helps limit thermal rise inside the enclosure. Using separate Ethernet and ControlNet links, the unit can exchange general plant data while maintaining deterministic communication with connected automation nodes.

The two digital outputs switch loads within a maximum propagation time of 400 µs, allowing precise reaction to encoder flags or interlock conditions. Protection is rated at IP20, so the unit must be installed in an enclosed panel free of conductive dust. Mechanical installation occupies 2 carrier slots on the RECO rack, leaving neighboring space for additional motion or I/O cards. The assembly weighs only 1.3 kg, which keeps the load on the rail hardware low. Cross-communication support and a CNS01 fieldbus node are included, and the unit has no memory expansion. Programs and connected modules must therefore fit within the onboard memory resources.
