Product Description:

The CSH02.1B-CC-EC-EC-NN-EC-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed inside drive cabinets, it acts as the primary control core for coordinated motion, process logic, and field communication in automated assembly lines, packaging units, and material-handling cells. Three optional slots allow the controller to accept add-on communication or safety modules without increasing the cabinet footprint.

At the board level, the unit draws a base power consumption of 17 W, enabling low-heat operation inside sealed enclosures. For direct sensor connection, it offers 3 analog inputs and 2 analog outputs that accommodate position or process feedback and proportional command signals. Discrete control is handled by 11 digital inputs plus 5 configurable I/O channels that can be set as inputs or outputs depending on the machine task. Two dedicated encoder rails provide 12 V and 5 V supplies, each capable of 500 mA, so incremental, sine-cosine, or SSI transducers can be powered without external regulators. The internal relay interface is rated for 30 V switching, and its current capacity is described below.

Field integration is anchored by the real-time SERCOS III master channel that synchronizes multiple drives over fiber or copper. Standard plant networks connect through a 100Base-TX port that shares the RJ-45 8-pin engineering socket for service access. High-resolution encoder feedback is accepted up to 400 kHz on the sine inputs, while square-wave tracks are processed at 1,000 kHz and resolver references are generated at 8 kHz. The relay path can continuously carry 1000 mA, letting the controller switch brakes or contactors directly. Unused pins can be reassigned through software, allowing the controller to adapt to different machine layouts.
