Product Description:

The Bosch Rexroth Indramat CSH01.1C-S3-EN1-NNN-NNN-S1-S-NN-FW is a modular control section in the CSH Advanced Controllers series. Used inside IndraDrive amplifier racks, the unit handles axis coordination, field communication, and integrated safety for electric servo systems. By processing position feedback and forwarding motion commands over high-speed buses, it supports synchronized drive operation and centralized diagnostics within the automation cabinet. This layout also helps reduce wiring between the control section and connected drive components.

Installation is simplified by a compact footprint. The housing measures 49.5 mm wide, 241 mm high, and 103 mm deep, which allows side-by-side stacking on DIN rails. Communication with the drive network is handled through the SERCOS III master interface, and two shielded ports use the RJ-45, 8-pin format for ring topologies over Ethernet cabling. Motor feedback enters through a D-Sub 15-pin connector that supports the HSF / RSF encoder protocol, while the internal HSF supply provides 8 VDC at up to 250 mA to power the transducer electronics. The card also supports direct connection of control signals through its onboard logic I/O, which helps keep cabinet wiring organized.

Functional safety relies on the Safety Technology I/O option, which is accessible through a D-Sub 9-pin plug, and its input circuit responds to 24 V at 3 mA. Safe power switching is provided through outputs rated at 24 V / 0.5 A, and a redundant relay path carries 24 VDC at 1 A for emergency-stop chains. For standard signaling, the module can drive external loads up to 500 mA, so interlocks or brake contactors can be energized directly from the board. Motion-related communication and safety-related switching are handled on the same control section.
