Product Description:

The CSH02.5B-CC-EC-ET-S4-EC-NN-NW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. As a scalable motion-logic control unit, it links drive modules, field devices, and safety hardware in industrial automation cells. The device’s role is to execute real-time motion sequences, collect field signals, and forward synchronized commands to connected servo drives, forming the central command layer inside multi-axis machines and production lines.

Three differential analog channels operate across a ±10 V range, allowing the controller to read process values such as torque demand or dancer position, and two analog output stages can return calculated setpoints to external actuators. Discrete signaling capacity starts with 11 digital inputs for limit switches and sensors, plus five ports that can be configured as either inputs or outputs. Each sourcing output can supply 500 mA, so small relays or indicator lamps can be driven directly. A SERCOS III master interface provides deterministic communication with drive amplifiers, while the built-in Ethernet socket uses a RJ-45, 8-pin connector and negotiates a 100Base-TX link for standard plant networks and service access.

For high-resolution position feedback, the unit carries a Multi-encoder interface that accepts several transducer formats without additional cards. Functional safety is implemented through Safe Motion, which enables certified monitoring functions when paired with compatible drives. Two probe inputs capture edge events, and the associated pulse-stretching circuit recognizes transitions as narrow as 4 µs. Multi-Ethernet connectivity allows simultaneous operation on PROFINET, Ethernet/IP, or Modbus TCP, while the integrated power section HMU05 supplies the controller and field I/O rails. Expansion is possible through three optional slots that accommodate additional communication or technology modules.
