Product Description:

The CSH01.1C-NN-ENS-NNN-MA1-NN-S belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. This controller manages a single drive axis and hosts local analog and encoder interfaces for motion tasks in industrial automation systems. By accepting IndraDyn, HIPERFACE, and 1 Vpp feedback sources, it links precision rotary or linear motors to higher-level motion sequences without an additional communication card. The arrangement supports local feedback handling in compact motion-control cabinets. Its mix of encoder support and analog expansion also fits systems that combine axis control with nearby sensor and actuator signals on the same machine section.

The board’s internal consumption is limited to 7.5 W, while the separate ENS supply draws 6 W. A momentary inrush of 4 A must be considered when sizing the upstream protective device. The installed MA1 analog I/O extension adds 2 W of load and provides 12-bit conversion. Two input channels accept signals over a symmetrical window, so sensors delivering up to ±10 V can be connected directly. Two output channels use the same range for actuator control, and no fieldbus layer is included. This layout keeps the controller focused on local signal handling rather than network-based communication.

The MA1 module provides 2 differential inputs, allowing high common-mode rejection measurements for position or process variables. For time-critical edge capture, the commanded output pulse can be set up to 100 ms. When serial diagnostics are required, the RS-232 interface supports cable runs up to 15 m and operates from 9.6 to 115 kBaud. The controller does not include integrated safety functions, so any required functional safety must be handled by external devices or higher-level PLC logic. This setup suits applications that need local analog processing and basic serial access in a compact enclosure, especially where simple point-to-point integration is preferred over added communication hardware.
