Product Description:
The CSH01.1C-SE-EN1-EN1-MD1-NN-S-NN-FW controller board is supplied by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Created for multi-axis drive systems, the card sits between the machine PLC and Rexroth power modules, translating network commands into precise motion references and gathering real-time feedback from connected motors. Its role in industrial automation is to coordinate position, speed, and process monitoring tasks while fitting into the manufacturer’s modular drive racks.
The board has an analog input resistance of 160 kOhm, a high impedance that prevents loading of external sensors wired to the board. Outbound reference signals are delivered at 5 V / 1 mA, supporting low-power trim functions on downstream drives. Internal dissipation remains limited to 7.5 W, minimizing cabinet heat. Motion data and cyclic setpoints are exchanged over the deterministic SERCOS II fiber ring, while resolver feedback on the EN1 channel is sampled at 4 kHz. Both encoder slots accept feedback units mounted on MHD or MKD motors, preserving plug-and-play compatibility. When the Digital I/O extension is installed, the controller can process pulse signals with widths up to 100 ms for product-detect or marker functions.
During startup, the assembly draws an inrush current of 4 A, so supply circuits must tolerate this brief surge. The integrated MD1 submodule provides 12 × 24 V digital inputs for limit switches and 8 × 24 V digital outputs for drive-ready or fault annunciation. Point-to-point diagnostics are handled through the built-in RS232 interface. A single 24 V / 3 mA onboard input offers a hardware inhibit line, and additional non-isolated outputs rated at 24 V / 0.5 A can drive status LEDs. One relay contact is available at 24 V DC / 1 A for galvanic separation of interlock chains. The controller does not include integrated safety technology, so external safety relays are required at the machine level.
