Product Description:

The CSH01.1C-PL-EN1-EN2-NNN-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a plug-in module, it hosts motion and safety processing that links Rexroth drive power sections with upper-level automation. Within an industrial cell, the unit coordinates axis position feedback, executes logic, and passes command data between drives and supervisory PLCs. This arrangement separates control functions from the power stage, which helps organize multi-axis systems that require centralized coordination and consistent signal handling.

The housing measures 49.5 mm deep, 103 mm wide, and 241 mm high, so a narrow cabinet slot can be reserved while maintaining sufficient airflow around the card. Sixteen parallel input channels accept discrete field signals, and the controller also provides 16 transistor outputs for status or interlock lines. Both groups terminate on a D-Sub 37-Pin connector, which simplifies panel wiring and keeps the interface concentrated on one connection point. For single-turn and multi-turn encoders on the EN2 port, the board supplies up to 350 mA, allowing low-power feedback devices to draw operating current directly. This mix of compact size, encoder support, and digital I/O is suited to cabinets where several axes must share limited installation space without adding separate interface hardware.

Encoder electronics are energized at 5.0 VDC, which supports TTL-level operation with typical incremental sensors, while resolver transducers receive 18.2 Vpp excitation at 4 kHz to maintain clean sine-cosine signals. The integrated safety core supports Safe Motion, allowing certified functions such as safe stop and safe limited speed when the peripheral safety connector X41, implemented as a D-Sub 9-pin female, is wired into the emergency-stop chain. For programming and diagnostics, the module provides an RS232 serial link so a local computer can access parameter data without occupying the fieldbus. Separate paths for feedback, safety, and serial access allow the control section to handle motion supervision and local diagnostic tasks at the same time.
