Product Description:

The CSH01.1C-SE-NNN-NNN-MD2-NN-S-XP-FW module is an automation controller manufactured by Bosch Rexroth Indramat and supplied within the CSH Advanced Controllers series. It serves as the central processing and field-level interface card inside IndraDrive systems, coordinating motion commands and discrete signals between the drive electronics and plant-wide control networks. This arrangement reduces the need for separate interface hardware in the cabinet. By combining high-speed serial communication with localized digital I/O, the unit streamlines machine sequencing, position feedback, and safety interlocking functions in industrial automation cells.

The controller communicates with higher-level PLCs through SERCOS II and supports a maximum bus rate of 16 MBaud, allowing deterministic data exchange for multi-axis motion profiles. An analog monitoring channel delivers a reference of 5 V for sensor feedback or drive scaling tasks. Local expansion is provided by the Digital I/O + SSI option; the MD2 board furnishes 16 digital inputs and 16 digital outputs that are arranged in an input group layout of 2 × 8 and an output group layout of 4 × 4. All MD2 signals terminate on a 44-pin D-Sub HD connector, and inductive loads can be switched directly because each relay path is rated for 24 V DC 1 A. The synchronous-serial interface supports absolute encoders and shares the same expansion plate so that position data can be captured without additional daughter cards.

For service access, an RS-232 port is available; it uses a Mini-DIN 8-pin plug, accepts cables up to 15 m, and handles transmission speeds up to 115 kBaud. The secondary SSI channel is limited to 1.5 m line length, connects through a RJ12 6-pin jack, and draws a supply current of 0.2 A from the controller backplane. Combined with the internal I/O layouts, these serial links allow the CSH01.1C card to synchronize drives, forward diagnostic data, and process discrete machine states without external multiplexers.
