Product Description:

Bosch Rexroth Indramat produced the CSH02.1B-ET-EC-EC-L3-DA-NN-FW. As a member of the CSH Advanced Controllers series, this unit mounts in the IndraDrive control section and supplies motion logic, fieldbus routing, and local I/O handling for multi-axis production lines. Its role in industrial automation is to synchronize drives, collect sensor data, and relay commands to higher-level PLCs, providing a compact supervisory layer that reduces cabinet space and wiring compared with separate standalone controllers.

The controller operates from a 24 V DC supply rail and draws only 17 W of base power, so cabinet thermal load stays low even when all electronics are active. Network connectivity is provided through Multi-Ethernet hardware that can be configured for EtherNet/IP, EtherCAT, SERCOS III, or PROFINET IO, allowing one platform to match different plant standards without add-on cards. A front-mounted microSD slot accepts removable memory for recipes and diagnostics. The ADVANCED control panel gives parameter access, while onboard I/O includes 11 digital inputs, 2 probe channels, 5 digital bidirectional lines, 3 analog inputs, and 2 analog outputs. When extra points are needed, a digital or analog I/O extension or the DA module that adds 6 DI, 2 DIO, 6 DO, 2 AI, and 2 AO can be fitted without enlarging the footprint.

Process outputs are sourced through transistor stages that supply up to 500 mA, and dedicated safety lines are limited to 350 mA to prevent excessive fault currents when the integrated STO (Safe Torque Off) function is triggered. Each probe channel can register edge events with a 4 µs pulse width, enabling precise position capture for high-speed motion tasks. These timing capabilities, together with the expandable I/O, support coordinated stop sequences and axis verification inside the drive system while keeping diagnostics reliable over long production cycles.
