Product Description:

The CSH01.3C-NN-EN2-MEM-CCD-NN-S-NN-FW is a single-axis controller card from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It installs in Rexroth drive racks to execute motion commands, interface with feedback devices, and coordinate axis sequencing inside automated cells or process lines. By combining command processing, field-level I/O, and encoder power on one board, the module reduces panel wiring and simplifies integration with higher-level PLCs. Its board-level design also supports compact multi-axis layouts where control functions and signal handling must remain concentrated within a limited cabinet area.

The card is powered from a control bus that supplies 24 V DC, and this low-voltage feed energizes the logic circuits while keeping the unit active during safe-torque-off states. Base consumption is limited to 8.5 W, which helps reduce heat buildup inside compact cabinets. For machine signals, it provides 1 differential analog input channel that can be mapped to speed or torque references, and 2 analog output channels that return real-time status such as position error. A maximum pulse width of 100 ms is accepted on high-speed latching inputs, allowing capture of index marks without missing narrow timing events. The memory capacitance between any output and 0 V is 10 nF/m, which helps limit coupled noise and maintain signal fidelity during rapid state changes.

A compact mechanical envelope supports dense mounting, with a depth of 49.5 mm, a width of 103 mm, and a height of 241 mm. These dimensions let multiple cards share a standard cabinet rail while still providing front access to terminals and diagnostic LEDs. The encoder port furnishes a stable 5 V supply, ensuring that incremental or absolute sensors receive regulated power even when external field supplies fluctuate. The narrow profile also leaves room for adjacent modules and cable routing at the front of the rack, which is useful in tightly packed motion-control assemblies.
