Product Description:

The CSH01.1C-SE-ENS-EN1-MEM-NN-S-NN-FW is a motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In an automation cell, it acts as the coordinating head by processing sensor feedback, generating setpoints, and distributing them to drive axes through the integrated SERCOS interface. By combining analog measurement, digital I/O handling, and high-speed fiber communication, the unit supports deterministic control of packaging, printing, and material-handling machinery. Its architecture lets one controller coordinate machine sequences and axis behavior from a single control platform.

The controller’s two differential analog inputs present an impedance of 160 kohm, so transducer circuits see minimal loading. Incoming signals are digitized in steps of 1.23 mV/inc, allowing fine measurement of position or pressure feedback. On the output side, the converter produces voltage increments of 19.5 mV/inc and can deliver those steps into loads of up to 5 kohm while supplying the required low output current for each channel. Cyclic data exchange with connected drives runs on the optical ring at 16 MBaud, which supports synchronized updates during closed-loop motion tasks.

The digital section supplies 11 optically isolated inputs for limit switches, sensors, or encoder markers, and it also provides four transistor outputs for status signaling or relay control. During power-up, the module can draw as much as 4 A before settling to a continuous power draw of 23.5 W, so the supply must support both startup and steady operation. Internal logic rails are supported by the ENS line and the EN1 HSF line, so external power must cover both auxiliary loads. The MEM interface can clock encoder data at 1 MHz over shielded cable runs up to 40 m, which helps preserve signal integrity for remotely mounted feedback devices.
