Product Description:

The CSH02.1B-ET-EC-EC-SB-DA-NN-FW is an advanced motion and I/O controller in the CSH Advanced Controllers series from Bosch Rexroth Indramat. It provides centralized processing for axis control and network communication, allowing coordinated movement and data exchange between servo drives, sensors, and supervisory PLCs in automated production systems. By combining high-speed fieldbus links with local analog and digital channels, the unit serves as the interface between drives and plant-level networks for real-time command execution and feedback.

The analog subsystem supports an output span of ±10 V, making the module suitable for standard velocity or torque references. Each voltage channel steps in 24 mV increments, while current feedback is digitized with a resolution of 12 bit. Separate voltage measurements are quantized at 14 bit. Four analog outputs can drive external actuators, and the controller’s five input channels accept corresponding process signals for closed-loop control. A base power use of 17 W keeps internal dissipation low, and the electronics draw their logic power from a 24 V DC control supply that can be wired from the drive cabinet bus.

On the discrete side, the module offers 7 configurable digital I/O points plus 6 dedicated outputs for status or interlock signals. The module also has 11 Type A inputs that are detected through rapid-scan logic, allowing additional sensors to be tied directly to the control task. Two probe inputs support position latching, and a pair of encoder interfaces accept incremental or absolute feedback sources for synchronized motion capture. Network connectivity follows the IEEE 802.3 physical layer, and the controller can communicate over sercos III/EtherCAT/EtherNet/IP/PROFINET IO, enabling integration with common drive and PLC environments. A communication-based safety interface exchanges safe motion states over the same buses while maintaining SIL-rated shutdown capability.
