Product Description:

The CSH01.1C-S3-EN2-NNN-NNN-NN-S-NN-FW is a single-axis motion and I/O controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It serves as the central command unit for one drive, processing position data, managing field devices, and exchanging real-time information with higher-level PLCs in automated production cells. This arrangement allows one controller to supervise motion commands, local signals, and feedback handling within the same compact platform.

This model communicates with drives through SERCOS III, while a separate RS232 service port supports serial communication over cables up to 15 m. One analog feedback path presents an input impedance of 160 kΩ, which helps minimize sensor loading, and the corresponding output stage can drive loads down to 5 kΩ. Each analog output step is resolved at 19.5 mV/inc, allowing fine voltage references for external amplifiers. Digital input channels accept 24 V / 3 mA signals for devices such as limit switches or probes, and transistor outputs deliver 24 V / 0.5 A for pilot contactors or indicators. The position loop is closed through an EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface, and a single internal axis kernel sequences the motion profiles. Timing resources include a maximum command pulse width of 100 ms and a 4 µs probe pulse, while an onboard relay rated at DC 24 V / 1 A provides an isolated fault or ready contact.

Total controller demand peaks at 7.5 W, which helps keep heat generation low in compact cabinets where multiple automation components may share limited space. Power-up draws an inrush current of 4 A, so the supply and protective devices must tolerate that brief startup load. The controller is intended for one axis and combines motion control, analog handling, digital I/O, serial service access, and feedback processing in one unit. Its signal interfaces support direct interaction with external sensors, switching devices, and the connected drive without adding redundant control paths.
