Product Description:

The CSH01.1C-NN-EN1-NNN-NNN-L1-S-NN-FW is a controller card produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. The module functions as the command layer inside multi-axis drive assemblies, translating machine directives into synchronized motor and I/O actions required for automated production lines. By hosting dedicated interface blocks and real-time processing, the unit coordinates motion sequences, monitors sensor feedback, and issues drive-enable signals to connected power sections.

Its internal supply subsection draws a base power of 7.5 W, which covers the standby demand of the logic and diagnostic circuits. An analog channel provides a reference level of 5 V for external potentiometers or sensor electronics that need a stable low-noise source. Command recognition is handled through digital inputs rated at 24 V / 3 mA, while actuator commands leave the board through digital outputs designed for 24 V / 0.5 A. This arrangement allows the controller to accept standard machine signals and switch relays or opto-couplers directly. The optional EN1 expansion consumes 6 W, so the added load must be included in cabinet power planning.

The controller responds to fast events with a probe pulse width of 4 microseconds and conditions resolver feedback with a carrier of 4 kHz at an amplitude of 18.2 Vpp. During startup, the logic draws an inrush current of 4 A for about 100 ms, so the incoming supply must tolerate a brief surge. Communication with external diagnostics is available through the serial port, which supports transfer rates up to 115 kBaud. For safety interlocks, a form-C relay rated at 24 V DC / 1 A is fitted. Secondary boards receive isolated power from the HSF header that delivers 8 V DC at 250 mA, plus an unregulated 2 W reserve on the L1 interface.
