Product Description:

The CSH02.5B-CC-EC-EC-NN-DA-NN-NW is an advanced motion and logic control unit manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for cabinet installation, the device handles axis coordination, signal conditioning, and real-time network tasks inside industrial automation cells. Its role is to receive encoder feedback, issue drive commands, and forward status information to supervisory PLCs. Because control and communication are combined in one unit, it can manage local machine functions while supporting synchronized motion across multiple axes with consistent cycle timing.

The controller operates as a SERCOS III master, providing deterministic bus scheduling to connected drives. Two multi-protocol encoder ports accept either a 5 V or a 12 V supply, and each rail can source up to 500 mA for supported feedback devices. Analog process values are refreshed every 250 µs, and the internal converter delivers 14-bit resolution, allowing fine torque or pressure references. Each digital output can sink current for relay drivers or indicator lamps, which helps the controller interface with common machine-level signaling devices.

Supplementary functions are handled by an EC module that draws only 1.1 W, preserving cabinet thermal budgets. The separate encoder rail remains stabilized at 6 W when the multi-encoder sockets are loaded. Configuration is performed through an 8-pin RJ-45 engineering port that adheres to the 100Base-TX Ethernet standard. Additional digital or analog I/O can be appended through the built-in expansion header, and every form-C relay on the board is rated for 1 × 10^8 cycles of mechanical life. The Ethernet service connection supports direct access for setup and diagnostics, while safety functions must be handled by external equipment when emergency stop or guard monitoring is required.
