Product Description:

The CSH01.1C-ET-ENS-ENS-MD2-NN-S-NN-FW is a controller card from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in IndraDrive power sections, it serves as the command layer that links fieldbus networks, local encoders, and onboard I/O so the drive can execute motion profiles and diagnostic routines inside automated machinery. This arrangement allows the controller to coordinate communication and signal handling within the drive system.

The card communicates through a Multi-Ethernet interface that supports industrial TCP/IP protocols carried on 100Base-TX wiring. When shielded twisted-pair cable is used, the Ethernet segment can extend up to 100 m between active nodes, giving flexibility in cabinet layout. An analog output channel is available with a full-scale range of 5 V, allowing reference signals to be sent to external devices. Each digital output line can source up to 500 mA, which is sufficient for driving small contactors or indicator lamps without an interposing relay. Digital inputs register a logical OFF below 5 V and a logical ON above 15 V, maintaining noise immunity on long wiring runs. Communication options include a 15 m RS-232 maintenance port, a D-Sub 15 ENS connector for resolver feedback, and an RJ12 six-pin SSI port that supplies 0.2 A to absolute encoders.

The MD2 expansion fitted on this model provides 16 digital inputs and 16 digital outputs for fast signal exchange with sensors and actuators at the machine level. For higher-current loads, the board includes a relay channel rated at 1 A continuous. Two standard encoder interfaces can be energized by the controller’s auxiliary supply of 24 VDC, eliminating the need for separate power supplies. These connections allow the controller to interface directly with local machine devices while supporting encoder feedback through the same control platform.
