Product Description:

The CSH01.2C-NN-NNN-NNN-CCD-L1-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. This plug-in control section is intended for coordinating drive and machine functions inside modular automation racks, where it processes motion commands, manages field signals, and passes data between networked nodes. Its role is centered on control and communication tasks rather than direct power conversion, which suits systems that separate logic functions from the power stage. A starting lockout safety feature prevents unintended motion until the correct enable sequence is received.

The analog front end accepts a symmetrical input span of ±10 V, allowing direct connection of speed or position reference signals without external scaling. Power for the onboard electronics must be supplied within the range of DC 19-30 V; this tolerance lets the unit ride through typical 24 V control-circuit fluctuations. During power-up, the module draws an inrush current of 4 A that can last up to 100 ms, so the upstream supply should be sized to handle the brief surge. Cross-device communication is handled through a CCD bus that uses a 100Base-TX physical layer, while an Ethernet-based engineering interface provides parameter access from host computers. The controller does not include a master fieldbus interface, and both option slot X4 and slot X8 are empty.

Panel space requirements are limited by a front width of 49.5 mm, an overall height of 241 mm, and a depth of 103 mm, enabling dense stacking inside 300 mm cabinets. The narrow housing helps preserve space for adjacent modules and internal cable routing in compact enclosures. Control outputs include a relay contact rated for 24 VDC, 1 A, which is suitable for enabling downstream contactors or feedback lamps. Serial diagnostics can be performed through the RS232 interface, which remains active even when network services are offline. The CCD backplane interconnect supports peer-to-peer data exchange between modules.
