Product Description:

The CSH01.1C-PB-ENS-NNN-MD1-L1-S-NN-FW is a modular motion-logic card from Bosch Rexroth Indramat that belongs to the CSH Advanced Controllers series. It occupies the master slot of a drive controller rack and supervises axis coordination, fieldbus exchanges, and local safety interlocks in automated machinery. A slim 49.5 mm front width and 241 mm height help the card fit inside standard control cabinets, while the integrated PROFIBUS interface streamlines plant-wide data flow and reduces the need for separate gateway hardware.

The electronic core draws only 7.5 W, which minimizes cabinet thermal load. Mechanical clearance is aided by the depth of 103 mm, allowing adjacent modules to share cooling airflow. All onboard logic and sensor circuits are supplied from an external 24 V source that may vary from 19.2 to 30 V, which supports long cable runs with voltage drop. For deterministic field communication, the controller uses a dedicated master channel with PROFIBUS-DP at selectable baud rates. Motion commands and status bits reach the power section through the MD1 terminal block, which accepts 12 × 24 V opto-isolated inputs for limit switches, sensors, and emergency commands. A matching set of eight outputs can energize relays or actuators at up to 1 A per contact, and a separate 24 V/1 A form-C relay supports direct machine interlocking.

An optional digital I/O extension plugs into slot 3 so the card can provide 8 × 24 V sourcing outputs when additional device drivers are needed. Feedback devices are read through the universal IndraDyn/HIPERFACE/1 Vpp/TTL port, and the port supplies encoders with 11.6 V at up to 500 mA, so external power injectors are unnecessary for typical sine-cosine or incremental transducers. Configuration and service tasks are handled over the built-in RS-232 serial jack, which supports standard 38.4 kbit/s diagnostics. A starting-lockout safety circuit disables PWM generation until all enabling inputs are validated, preventing unintended motion during power-up.
