Product Description:

The CSH01.1C-NN-ENS-NNN-NNN-S1-S-NN-FW is a single-axis motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The module acts as the command level between higher-level PLCs and Rexroth power sections, providing real-time position, velocity, and safety supervision for servo drives in industrial automation lines. By integrating encoder handling, analog conversion, and safe I/O on one card, it simplifies cabinet wiring and shortens system cycle times. This layout suits machines that need coordinated motion control and local signal processing without adding separate interface modules. It is suitable for transfer systems, indexing stations, and other equipment that depends on tightly timed axis control.

It offers an analog input resistance of 160 kΩ, so signal sources see minimal load. The 16-bit converter provides a step size of 1.23 mV/inc, giving fine granularity for pressure or tension feedback loops. On the output side, the card can source up to 1 mA per analog channel, and each output step is 19.5 mV/inc, enabling precise setpoint generation for external drives. Digital outputs are rated for sink currents up to 500 mA, allowing direct actuation of contactors or lamps without relays. The encoder interface uses a D-Sub 15 female connector and supplies the sensor with 12 V regulated power. During power-up, the board draws a typical inrush current of 4 A, and the pulse lasts no longer than 100 ms, limiting stress on cabinet breakers.

The four digital outputs share a combined current budget of 1000 mA, while internal logic and interface circuits consume only 14.5 W under normal load. The probe input can recognize edges as short as 4 µs, supporting high-speed registration tasks such as print-mark detection. Serial diagnostics are available through an RS-232 port that reaches 115 kBaud over cable lengths up to 15 m. Safety signals enter through a D-Sub 9 female connector, and the safety I/O rail can deliver 1.6 A to external devices. This combination supports compact cabinet layouts that need motion control, diagnostics, and safety connections on one board. The board can also support auxiliary safety devices without requiring a separate interface card.
