Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-S1-S-NN-FW control section belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It plugs into an IndraDrive power unit and forms the processing core that executes motion sequences, handles fieldbus traffic, and supervises built-in safety channels for multi-axis servo systems. In an automation cell, the module coordinates real-time axis commands while routing encoder feedback and discrete I/O, thereby replacing separate PLC and safety relay functions with a single compact board.

During normal service, the controller draws only 7.5 W, so cabinet heat generation is minimal. Startup still demands an inrush of 4 A, which must be considered when sizing the supply. Command exchange with decentralized drives and HMI stations is handled over SERCOS III through two RJ-45 ports that support line or ring topologies. Each analog input presents an impedance of 160 kΩ, which helps prevent signal loading when connected to delicate sensor circuits. Digital outputs can source or sink up to 24 V / 0.5 A, allowing direct actuation of contactors or optical isolators without auxiliary amplifiers. An additional Mini-DIN RS-232 service socket supports local service access and diagnostic capture without occupying the deterministic network.

For reference generation, the analog output delivers 5 V / 1 mA with calibrated linearity. The integrated encoder connector feeds the transducer with a regulated 11.6 V supply and routes differential position signals back to the motion kernel. Single-shot timing functions are available with pulse widths up to a maximum of 100 ms, which is useful for index table clamps and gate interlocks. Form-C relay contacts are rated at DC 24 V / 1 A, giving the board a galvanically isolated channel for drive enable chains or alarm beacons. Dedicated Safety Technology I/O terminals monitor 24 V inputs at 3 mA and publish status over the same SERCOS cycle, completing the functional safety layer without external wiring complexity.
