Product Description:

The CSH01.1C-S3-ENS-NNN-MA1-NN-S-NN-FW is an axis and logic controller card developed by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in a modular drive stack, the card provides real-time axis control, fieldbus communication, and local I/O processing for industrial automation equipment such as packaging or material-handling lines. By combining motion coordination with programmable logic in a single slot, it reduces cabinet space while maintaining deterministic performance on multi-drive systems.

At the communication level, the controller links to servo drives over the SERCOS III real-time network through two RJ-45 8-pin S3 ports. Serial diagnostics are handled by an RS-232 interface that supports data rates up to 115 kBaud and cable runs as long as 15 m. The board draws only 7.5 W from the power bus, minimizing heat inside the enclosure. A dedicated encoder socket uses a 15-pin D-Sub female connector and delivers a regulated 12 V supply to feedback devices. Each of the onboard high-side digital outputs can source up to 500 mA, and the relay contacts switch DC loads to isolate field devices. Command signals are passed to adjacent inverters through deterministic cyclic data, ensuring synchronous motion.

The MA1 mezzanine section provides two analog inputs and two analog outputs for process signals. Each input presents an impedance of 1000 kΩ and has a 12-bit resolution. The outputs can drive loads down to 1 kΩ, allowing precise reference generation for external amplifiers or sensors. A Form C relay is integrated for discrete control tasks, and its contacts are rated for currents up to 1 A at DC 24 V. Internal buses transfer sampled data to the main processor without burdening the real-time network, so motion loops remain deterministic even when the analog channels are active.
