Product Description:

The CSH02.5B-CC-EC-ET-S4-EM-NN-NW is a motion and logic controller manufactured by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. In an automation cell, it coordinates multi-axis drives, peripheral sensors, and plant networks, serving as the central unit that issues trajectory commands and gathers real-time status data from connected devices. It combines motion control with logic handling in one platform, which helps keep command flow and feedback exchange organized across the machine. This arrangement is useful when motion sequences, signal evaluation, and network communication must be handled at the same time without splitting those tasks across separate controllers.

Within its I/O block, the controller delivers an analog output resolution of 24 mV/incr on two voltage channels, allowing precise command scaling for proportional actuators. It offers 11 digital inputs that accept sensor states and interlock signals, while each digital output can source up to 500 mA to drive contactors or stack lights directly. For deterministic data exchange, the built-in Ethernet PHY supports 100Base-TX, and axis synchronization is handled by a SERCOS III master bus running at sub-millisecond cycle times. Five configurable I/O points, two probe inputs for edge-triggered position capture, encoder emulation, and multi-encoder feedback further extend its signal handling capability. This mix allows the unit to work with both straightforward discrete signals and more timing-sensitive position functions.

System expansion uses Multi-Ethernet routing that combines EtherNet/IP, PROFINET, and Modbus TCP on a shared backbone accessed through an RJ-45, 8-pin connector. Three optional slots accept additional fieldbus or axis cards, and the multi-encoder interface supports EnDat, SSI, or incremental transducers without extra converters. A dedicated Safe Motion channel monitors speed, direction, and safe stop parameters, reducing external safety wiring. Diagnostic LEDs and software tools provide status indication, and the matched power section HMU05 mounts on the same backplane to share the DC bus and brake energy. The shared backplane arrangement keeps network expansion and power integration within the same control structure.
