Product Description:

The CSH02.1B-ET-EC-EC-SB-EC-NN-FW is an advanced motion controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed for cabinet installation, it coordinates multiple servo drives and field devices over deterministic Ethernet networks. Within an industrial cell, it can replace a standalone PLC by calculating trajectories, exchanging safety status, and issuing synchronized start or stop commands. This arrangement allows automated machinery to run coordinated cycles with tight positional accuracy across several connected axes and peripheral devices.

Its base power draw is only 17 W, which helps limit heat buildup in compact enclosures. Programmable logic is supported by 5 configurable digital I/O points that can switch direction through software, while another bank provides 7 dedicated digital inputs for fixed interlocks or sensor lines. Each high-side output can source up to 500 mA, allowing direct actuation of compatible external devices. The controller’s multi-Ethernet core recognizes industrial stacks such as Sercos III, EtherCAT, EtherNet/IP, and PROFINET IO, allowing the same hardware to operate across different plant network standards. Two isolated Ethernet ports support line or ring topologies, which helps organize network routing and maintain communication paths between connected machine sections.

Segment wiring can span 100 m between nodes, and the board limits initial energization to <5 A for a brief 1 ms inrush to help protect supply fuses. Safe torque and speed signals are carried over the Safe Motion Bus, allowing coordinated shutdown behavior across linked axes. Three analog inputs, two analog outputs, and three multi-encoder interfaces share a D-Sub 15-pin female socket that can furnish 5 VDC or 12 VDC sensor supply. This shared connection point allows several feedback and signal channels to be handled at the controller without separate interface modules, and it also helps shorten cable runs inside the cabinet.
