Product Description:

The CSH02.1B-ET-EC-EC-NN-NN-NN-FW is a motion-logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It directs servo drives, captures encoder feedback, and exchanges process data so automated stations can synchronize axes and peripheral sensors from one device. By combining program execution, fieldbus routing, and I/O conditioning in a single rack-mount module, it serves as the central coordinator for packaging lines, pick-and-place robots, and indexing tables. This layout reduces the need for separate interface modules when motion control and signal handling must be managed from the same control layer.

Two differential analog input channels accept a swing of ±10 V, enabling direct connection of position transducers or tension cells. The same voltage span is available at the analog outputs for speed or torque reference commands. The baseboard offers 11 digital inputs for end switches and fault signals, while five terminals can be reassigned as 5 configurable digital I/O points for application-specific handshakes. The controller uses Multi-Ethernet and features 2 Ethernet ports that support daisy-chain or ring wiring and comply with the IEEE 802.3 physical layer. Additional resources include dual probe inputs, a D-Sub 15-pin female connector for quadrature or absolute encoder signals, and a secondary multi-encoder interface for gantry master-slave arrangements.

Each sourcing driver can deliver up to 500 mA, allowing the board to energize contactors or lamp stacks without external relays. Internal electronics draw only 17 W, minimizing cabinet heat even when expansion hardware is added to the backplane’s 3 optional slots. Logic circuits and field devices share a common machine bus that feeds the unit with a regulated DC 24 V. Probe inputs and multi-encoder support help the controller handle timing-sensitive motion tasks, and the absence of integrated safety technology allows external safety relays to be selected as needed for the application.
