Product Description:

The CSB02.1B-ET-EC-PB-NN-EC-NN-AW belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. It is a compact single-axis drive controller that coordinates motion, fieldbus communication, and local I/O for industrial automation cells. By combining network connectivity with onboard signal conditioning, the unit provides a central point for command processing, feedback evaluation, and peripheral wiring inside the control cabinet. It is intended for applications where one axis must exchange data with higher-level networks while also handling local device signals.

The control section is powered from a 24 V DC supply and offers three analog inputs and two analog outputs for process variables that require proportional scaling. Five configurable I/O channels can be set as sourcing or sinking to match sensor requirements, while the unit also provides 11 digital inputs for fast edge detection. Two independent transistor outputs share a common driver path rated at 500 mA for relays or indicator lamps. Network integration is handled through a dedicated fieldbus interface that supports PROFIBUS diagnostics and cyclic data exchange, and a separate Ethernet port that uses Multi-Ethernet communication for flexible protocol selection. Dual multi-encoder ports accept incremental or absolute feedback so the controller can close position and velocity loops directly. This mix of analog, digital, and encoder connections supports actuators, sensors, and feedback devices from the same control platform.

The Ethernet interface uses the 100Base-TX physical layer and maintains deterministic transfer across cable runs up to 100 m. The twisted-pair connection uses an RJ-45, 8-pin connector, which supports standard patch-cable installation. Two probe inputs capture position latches for stamping or labeling stations, and the internal relay circuit can switch auxiliary loads up to 30 V without an external interposing contactor. The unit does not include a safety option. The probe inputs are useful when the machine must record exact positions in relation to product marks or tool events.
