Product Description:

The CSH01.1C-S3-EN1-NNN-NNN-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in IndraDrive power modules, it forms the real-time interface between motion commands and motor actuation in conveyors, pick-and-place axes, and packaging lines. The board conditions analog and digital signals, manages communication to the factory network, and delivers the timing data needed for closed-loop positioning tasks in industrial automation equipment.

Deterministic exchange with the drive and other nodes is handled through the SERCOS III interface, which supplies synchronized telegrams for position, velocity, and diagnostic data every cycle. The logic electronics draw 7.5 W from the 24 V control rail, and the first connection moment can briefly demand 4 A of inrush current that the cabinet supply must tolerate. For slow-changing reference values, the controller provides an analog output channel that sources up to 1 mA with a granularity of 19.5 mV per increment. Time-based functions such as camming limits can accept command pulses as wide as 100 ms, ensuring that extended level signals are still recognized by the controller.

Field-level resources are completed by an analog input path that presents 160 kΩ of resistance, minimizing the load on external sensors, while a probe circuit offers a timestamp accuracy of 1 µs for event capture and can accept trigger pulses lasting 4 µs. Total current available to peripheral switches reaches 1000 mA across the grouped digital outputs, while each individual bit can deliver 500 mA, and the board can furnish up to 1.1 A to auxiliary I/O rails. An integrated relay carries loads up to 24 V DC, 1 A, and encoder channels supply 8 V DC for resolver or HSF feedback devices. No dedicated safety technology is implemented, so external safety relays must be provided where required.
