Product Description:

The PPC-R22.1N-T-G2-P2-NN-FW is a control unit produced by Bosch Rexroth Indramat for the PPC Controllers series. Mounted in centralized motion systems, it sequences axes, gathers machine signals, and links local drives with plant-level networks through its onboard communication ports. The integrated layout combines control, communication, and essential I/O in one enclosure, which helps reduce cabinet wiring and keeps related functions in a single hardware platform. In centralized machine architectures, it serves as the control point between field signals, coordinated axis commands, and supervisory data exchange. That role makes it suitable for systems where several motion axes and discrete machine signals must be managed from one location.

Operating from 24 VDC, the module draws up to 1.2 A. It has 3 digital inputs for sensor signals and 2 digital outputs for relay actuation, while the IP20 enclosure protects the terminals inside a cabinet. An input delay of 50 µs supports fast feedback handling, and the internal driver stage supplies 0.5 A per output without external amplifiers. The Profibus DPS01 slave interface transfers setpoints, onboard Ethernet provides access to parameters and network communication, and two serial ports support legacy devices. Input channels tolerate 24 V sensor power without dedicated isolators, and a grounding bar helps support EMC-compliant installation. This mix of power, I/O, and communication features allows the controller to interface with sensors, relays, networked drives, and older serial peripherals at the same time.

The controller supervises up to 40 drives. Each output reaches its new state within 500 µs, and DC bus conditioning limits ripple to 4 Vpp to reduce the chance of undervoltage faults during regeneration. A 4-digit alphanumeric display presents status codes for local diagnostics, and three expansion slots accept option cards for added functions such as high-speed counting. No memory expansion is installed, so those slots remain available for application-specific modules when needed. These operating limits support predictable timing in systems that coordinate multiple drives and machine signals.
