Product Description:

The CSH01.1C-S3-ENS-NNN-MD2-L1-S-NN-FW is a modular motion and I/O controller card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The board is inserted into a Rexroth power section so that it can calculate motion profiles, manage axis coordination, and supervise machine safety functions during industrial automation cycles. In practical use, it bridges higher-level PLC instructions with drive inverter hardware, delivering precise trajectory commands while collecting real-time status data from encoders and field devices. This arrangement lets one control platform handle synchronized motion and local signal exchange without requiring a separate external motion computer.

This card links to the drive network through SERCOS III, a deterministic Ethernet protocol that maintains cycle times down to 250 µs for coordinated multi-axis motion. Each analog feedback channel presents 160 kΩ of input resistance, reducing loading on external transducers and improving signal fidelity. The analog output terminals supply up to 5 V / 1 mA, which is suitable for reference signals to external amplifiers or valve controllers. Internal logic and communication functions draw only 7.5 W of control power, helping keep the cabinet thermal load low. For position capture, the probe input achieves 1 µs timing accuracy, which helps the control system correlate external machine events with actual axis position.

Encoder feedback connects via a D-Sub 15 socket, and the board supplies the transducer with 11.6 V at up to 500 mA so high-resolution encoders remain powered without separate supplies. The integrated MD2 module brings 16 digital inputs and 16 digital outputs, and each output can deliver 0.5 A, enabling direct actuation of contactors, indicator lamps, or pneumatic valves. Network redundancy is supported by a ring topology over the 100Base-TX copper link through dual RJ-45 ports. During startup, a hardware lockout compliant with Stop Category 0 prevents unintended motion until an external 24 V enable signal, sensed at 3 mA, is present.
