Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-S2-S-NN-FW is a motion-control and I/O processing module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for installation in drive cabinets, it links field devices to higher-level automation by using the built-in SERCOS interface and dedicated encoder channels. Within an automated line it issues real-time commands to drives, collects status data, and executes the Safe Motion functions required for personnel protection while maintaining process continuity.

During operation the controller draws only 7.5 W from the cabinet supply, so thermal load and auxiliary power requirements remain low. Communication with drives and PLCs is handled over the SERCOS II fiber link, providing deterministic timing for synchronized axis updates. At start-up an inrush of 4 A must be considered when sizing fuses and power wiring. Each digital output can source or sink up to 500 mA, and the driver absorbs inductive energies to 400 mJ when coils or brakes are released. The 24 digital inputs register an off state below 5 V and switch on above 15 V, eliminating false triggers caused by electrical noise. For simulation or feedback replication tasks, the emulation channel can toggle at up to 1 MHz, drive 20 mA, and maintain signal integrity over cables as long as 40 m.

The encoder interface permits differential sensing over cable runs up to 75 m, which simplifies layout on large machines without degrading signal integrity. Its termination of 120 Ω matches standard twisted-pair impedance, and the onboard supply delivers 11.6 V at up to 500 mA for external transducers. TTL counters accept pulse trains to 400 kHz, so high-speed position feedback or spindle monitoring can be processed directly while Safe Motion logic supervises limit violations and overspeed events.
