Product Description:

The CSH01.1C-SE-EN1-EN2-NNN-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into a Rexroth drive rack and governs one mechanical axis, issuing setpoints, monitoring feedback, and executing safety logic required in automated assembly lines, packaging machines, or material-handling cells. By concentrating motion coordination on a dedicated card, it frees the plant-level PLC from high-speed servo tasks and ensures deterministic real-time performance.

This card is configured for single-axis operation, so each installed unit directs one motor or actuator without axis multiplexing. Command and feedback data move through fiber-optic cables, shielding the signals from electrical noise common in inverter cabinets. The real-time layer follows the SERCOS II protocol, which synchronizes drives at cycle times down to microseconds and supports hot-plug diagnostics. Logic electronics draw power from a field supply of DC 24 V, and this low voltage simplifies control-cabinet wiring and isolation design. Under continuous operation the module dissipates only 22.5 W, reducing enclosure heat load and allowing dense multi-axis stacking. A built-in standard operator panel provides local parameter access for setup and diagnostics.

Safety functions are handled through the Safety Technology I/O package, which limits switching events to a maximum pulse width of 100 ms and interfaces with external emergency devices through a D-Sub 9 female connector. The safe output stage can source up to 1.6 A on the dual-channel I/O line and sink a controlled 0.5 A toward field actuators such as contactors or valve coils. Internal relays rated at 1 A allow redundant circuit interruption, while the power rail withstands a typical inrush of 4 A when the 24 V bus is first energized. These electrical limits help size upstream fusing and support predictable shutdown behavior in hazardous motion scenarios.
