Product Description:

The CSH01.1C-ET-ENS-NNN-NNN-NN-S-NN-FW controller is produced by Bosch Rexroth Indramat in the CSH Advanced Controllers series. This motion and logic module is intended for use inside IndraDrive power sections, where it executes axis control, fieldbus communication, and I/O processing for automated machinery. By managing encoder feedback, discrete signals, and high-speed Ethernet networks, the unit coordinates servo drives, sensors, and supervisory PLCs within a distributed automation architecture. Its compact format allows front-door mounting in control cabinets without additional cooling hardware.

It draws 7.5 W from the 24 V control supply, which helps limit cabinet heat and standby load. The local I/O bank includes 11 digital inputs, and each input registers an ON state once the terminal sees 15 V, while switching to OFF below 5 V for direct connection of PNP sensors without extra conditioning. A single differential analog input channel is provided for process values such as torque or pressure feedback. For time-critical capture, the TTL counter accepts pulses up to 400 kHz, enabling accurate position latching from encoders or code wheels. Control data exchange occurs over Multi-Ethernet, supporting simultaneous SERCOS III, EtherNet/IP, and PROFINET traffic.

Two voltage-scaled analog outputs deliver setpoints with a resolution of 19.5 mV/inc, and each new value is updated within 10 µs, helping keep drive commands synchronized with the control loop. At power-up, the module withstands an inrush of 4 A without nuisance tripping of the auxiliary supply, while an internal relay rated for 1 A at 24 VDC can forward ready or fault signals to external safety circuits. The D-Sub 15 encoder connector supplies 11.6 V excitation to absolute or incremental transducers, completing the feedback path for connected devices.
