Product Description:

The CSH01.1C-S3-ENS-EN2-MEM-S1-S-NN-FW controller is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in multi-axis drive racks, it translates motion commands from a central PLC into real-time setpoints, feedback, and safety signals for servo inverters and peripheral I/O. By combining fast logic, analog references, and galvanically isolated digital channels, the unit serves as the coordination layer that keeps industrial machinery synchronized. Because these functions are integrated in one control stage, the drive rack can exchange motion, status, and interlock information through a single controller module.

During power-up, the module draws an inrush current of 4 A and then settles to a base consumption of 7.5 W, which reduces the steady thermal load inside the cabinet. Two analog outputs can source up to 1 mA or provide a voltage reference of 5 V, allowing direct connection to servo amplifiers or signal converters. Eight digital sourcing outputs provide up to 500 mA each and can safely dissipate 400 mJ of inductive load energy without external clamps. A ready relay rated at 24 VDC and 1 A can report controller status to interlock circuits, while a separate safety pair can switch 0.5 A for dedicated stop-chain signaling. This arrangement allows one slot to handle command output and discrete control functions at the same time.

The remaining interfaces extend signal reach throughout the cell. The EN2 port is powered by 5.0 V at 350 mA and supports a sense-line length of 75 m, while the ENS outlet delivers a stabilized 11.6 V at 500 mA for active encoders. For high-resolution capture, the MEM channel streams square waves at a peak frequency of 1 MHz, and each pulse can be stretched to 100 ms for slower receiving devices. Up to 40 m of cable can be used on this link without noticeable edge degradation. This helps when encoders and receiving electronics are mounted away from the main control cabinet.
