Product Description:

The CSH02.5B-ET-EC-EC-L3-NN-NN-NW is an automation controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. The module supervises multi-axis drive systems, translating machine-level instructions into real-time current, speed, and position references for servo inverters. Its design allows the controller to occupy a compact slot in a control cabinet while providing deterministic command exchange between motion devices and higher-level PLC or HMI layers. This arrangement supports coordinated machine operation where fast updates and stable communication are required across multiple axes.

Its analog section accommodates input signals across a bandwidth of 1.3 kHz, sampled with 14-bit resolution. Outgoing command voltages are processed with a conversion time of 750 µs and a granularity of 24 mV per increment, while the module provides 2 independent analog outputs for drive reference or process feedback. Eleven digital inputs accept limit switches, probe triggers, or encoder zero pulses, so the controller can react to machine events without external signal conditioning. Two eight-pin RJ-45 connectors are placed on the front panel for network access, and a relay channel can switch loads up to 30 V for contactors or signal lamps.

It offers 5 configurable digital I/O lines that can be reassigned in software for handshake, latch, or event functions. The Ethernet circuitry complies with the 100Base-TX standard and supports cable runs up to 100 m, enabling direct connection to plant switches without repeaters. A built-in safety circuit delivers the STO function, which removes drive enable signals when the emergency chain opens. The controller is supplied without a control panel, so a separate operating interface can be selected when local visualization or manual interaction is needed.
