Product Description:
The CSH02.5B-ET-EC-NN-S4-DA-NN-NW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. In an IndraDrive system, this controller supplies the processing and communication layer that links motion axes, feedback devices, and higher-level PLCs. It docks to the HMU05 power section, allowing centralized parameter handling and coordinated drive operation in automated machinery. This arrangement lets the controller exchange commands and status data between the machine control and the drive hardware. It is suited for applications where synchronized motion, feedback processing, and network communication must be handled in one control layer.
The controller accepts differential process signals through an analog input range of ±10 V and an analog current range of 0–20 mA, so typical transducers can be connected without extra scaling hardware. It also provides an analog output range that matches the voltage input range, while each digital output can sink or source up to 500 mA. These interfaces support setpoint transmission, status signaling, and sensor monitoring without requiring separate signal converters. Multi-Ethernet communication is supported through a port that follows the 100Base-TX standard and uses a shielded 8-pin RJ-45 connector. A multi-encoder interface accepts EnDat, SSI, or resolver feedback, allowing the controller to supervise axis position through one hardware interface and support mixed feedback types on the machine.
Dedicated connectors organize the I/O layout across the controller. The X35: 2 AI + 2 AO + 4 DIO connection handles mixed analog and digital process signals, while the X37: 6 DI + 2 DIO + 6 DO connection adds more discrete control points. The X38: 2 AI + 2 AO connection expands analog capacity, and functional safety is integrated through Safe X41: 2 In + 2 Out channels for commands such as STO or SS1. The safety channels are built into the controller, which reduces the need for separate external safety hardware for basic stop functions. When additional field signals are required, a digital or analog I/O extension module can be attached to increase device capacity while preserving deterministic response times.
