Product Description:
The CSH01.3C-PB-EN2-EN2-CCD-NN-S-NN-FW is an automation controller card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed as a plug-in module inside compatible IndraDrive power sections, it acts as the central logic element for axis motion, sensor feedback, and fieldbus communication in packaging, printing, and material-handling equipment. By linking command processing with real-time feedback handling, the card supports precise servo positioning and consistent data exchange with higher-level control hardware. It processes command, feedback, and diagnostic information in one location, which helps the drive respond quickly to motion changes on individual axes.
The card exchanges cyclic data with higher-level devices through PROFIBUS-DP, and the interface reaches 12 MBaud to reduce network latency. Its idle power draw is 8.5 W, and the supply must tolerate an inrush of 4 A when the backplane energizes. During cross-communication between drives, the unit acts as the master node and uses the IEEE 802.3 standard to package status words. A counter channel accepts square-wave references up to 1000 kHz, supporting registration control in cut-to-length lines. Both encoder sockets handle EnDat 2.1, 1 Vpp, or 5 V TTL signals, and a pulse width limit of 100 ms protects the optocouplers. This arrangement supports communication with plant networks while still accepting direct feedback from rotary or linear measuring devices.
Field-level I/O connects to the second encoder header, which also supplies 5.0 V at up to 350 mA for sensor excitation. The return path presents an input resistance of 120 ohms and a load resistance of 35 ohms, which help reduce line reflections on long cables. Form-C relay contacts on the front edge are rated for DC 24 V / 1 A, providing a galvanically isolated way to switch brakes or ready lamps under low current. This variant is not equipped with safety technology, so external STO modules are required where functional safety is mandatory. The relay output is suited to signal-level switching rather than high-power loads, so external power components are still required for larger actuators.
