Rexroth CS351S-G IL

The CS351S-G IL is a single-channel tightening controller from Rexroth CS351 compact system series, built for precision spindle tightening control in safety-critical assembly lines. This CS351S-G IL accepts 120V / 230V single-phase AC input, rated at 10A at 120V and 5A at 230V with nominal power of 1200W. The CS351S-G IL comes with a high-resolution integrated TFT display, which shows real-time torque, angle values and tightening curve graphs directly on the front panel for operators.

This CS351S-G IL features IP54 enclosure protection and EMC severity level IV, making it stable against dust, splash and electromagnetic noise on production floors. The CS351S-G IL supports Ethernet and USB communication ports, enabling tightening data logging, recipe backup and connection with PLC, SCADA and factory MES systems. Multiple tightening strategies can be stored inside the CS351S-G IL, supporting torque control, angle monitoring and yield classification for bolt joint quality traceability. Service technicians can adjust parameters, download programs and review fault records quickly on the CS351S-G IL during commissioning and troubleshooting.

The CS351S-G IL is widely used for automotive assembly, powertrain workshop and industrial fastening stations that require repeatable, auditable bolt tightening results. The IL suffix of this CS351S-G IL indicates the special interface variant for spindle connection. Many manufacturing plants stock the CS351S-G IL as spare controller for replacement and retrofit of existing Rexroth tightening systems.
