Product Description:

The CSH01.2C-PB-NNN-NNN-CCD-L1-S-NN-FW is a modular motion and logic controller from Bosch Rexroth Indramat and is part of the CSH Advanced Controllers series. Installed in Rexroth drive racks, the CSH01.2C-PB-NNN-NNN-CCD-L1-S-NN-FW coordinates axis control, fieldbus exchange, and local safety so that servo drives and machine I/O operate in a synchronized sequence. It is intended for industrial automation tasks where deterministic communication and integrated safety are required, such as packaging lines and material-handling cells.

The controller’s analog acquisition circuit presents an input resistance of 160 kΩ, which limits source loading when process transducers are connected. Internal consumption remains low because the base electronics require only 8.5 W, which helps reduce cabinet heat buildup. At power-up, the supply must withstand an inrush current of 4 A that lasts about 100 ms, after which the module settles to its nominal draw. Engineering access is provided over Ethernet through a 100Base-TX port on an RJ-45 8-pin connector for parameter access and diagnostics. A separate mini-DIN port carries RS-232 for serial diagnostics, and a CCD fiber line supports messaging between drive controllers.

For discrete machine interfacing, the unit provides a digital output stage rated at 24 V / 0.5 A and an electromechanical relay that switches up to 24 V / 1 A, supporting lamp stacks or contactors. Field-level coordination with drives and remote I/O is handled by a master channel based on PROFIBUS, while peer-to-peer drive sharing uses the cross-communication line designated CCD. A D-Sub 9-pin female connector carries safety signals that implement a starting lockout function compliant with Stop Category 0 under EN 60204-1. The combination of controlled inrush behavior, low base power demand, and multiple communication ports helps the module fit power-constrained multi-axis cabinets without added interface cards.
