Product Description:

The CSH01.1C-PB-NNN-MA1-MD1-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It slides into compatible drive assemblies to handle axis processing, fieldbus communication, and local input and output tasks inside industrial machinery. In operation, it links drive functions with higher-level control commands so coordinated motion sequences can be processed across automated equipment. Its compact plug-in format keeps control functions inside the drive system, which helps cabinet layouts stay organized when multiple axes and local signals must be managed together.

Fieldbus traffic is handled through PROFIBUS, and the board presents a D-Sub 9-Pin female port for that network. This interface supports data exchange with upstream control hardware, while the lack of an encoder interface means axis feedback must be processed by another module in the drive stack. The MA1 analog section provides 2 differential inputs and two voltage outputs, and both directions use a ±10 V range with 12-bit resolution for 4,096 discrete signal steps, which suits command values and measured signals that require stable analog handling.

Discrete control is provided by 12 x 24 V sourcing inputs and 8 x 24 V high-side transistor outputs on the MD1 channel set. These circuits draw up to 1.1 A max from the module’s onboard supply, which must be fed with DC 19 to 30 V through the backplane so connected sensors and switching signals can be processed reliably. For diagnostic access or parameter transfer, the unit includes an RS232 service line that terminates on an 8-pin Mini-DIN female connector, allowing direct local communication without adding a separate service interface card.
