Product Description:

The PPC-R22.1N-T-N1-N2-NN-FW control unit from Bosch Rexroth Indramat belongs to the PPC Controllers series and functions as the motion and process coordinator in distributed automation cells. Supplied as design version 1, the module is built in the compact RECO housing and weighs 1.3 kg, making it suitable for DIN rail mounting or panel cavities where space is limited. A four-digit alphanumeric front display provides local status indication, while three expansion slots accept option hardware such as the dedicated PLS card. The base model is shipped without memory expansion and uses a 1.5 mm² power connector for its DC supply.

The controller is energized by a regulated 24 VDC source. Under worst-case loading, the internal circuitry draws up to 1.2 A, so the power supply must be sized to avoid undervoltage faults. Within that operating range, the permissible ripple on the input line is 4 Vpp, which helps protect the logic from transients created by switching loads on the same bus. For networked installations, the unit offers a 100Base-TX interface that transfers real-time data at 100 MBaud. Two rear serial ports support legacy device connections and can be set as high as 115200 baud without additional hardware. These electrical limits affect cabling, fusing, and noise-suppression measures around the cabinet.

Control signals are handled locally through 3 digital inputs that accept sensor or limit-switch states and through 2 digital outputs. Each output can source up to 0.5 A, allowing direct actuation of relays or indicator lamps without external drivers. The front cover carries the same IP coding as the case; an IP20 rating means live parts are guarded from finger contact, but the unit must be mounted inside a closed cabinet. This arrangement allows the controller to read basic machine states and switch low-current field devices directly from the unit.
