Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PB-EN2-NNN-MEM-S2-S-NN-FW, a programmable motion and safety controller in the CSH Advanced Controllers series. Installed in drive racks, it supervises axis modules, manages fieldbus traffic, and executes safe-motion functions so machinery can maintain coordinated positioning, speed limitation, and emergency torque shutdown within one compact control layer. Its role in an automation line is to translate higher-level commands into deterministic drive signals while also capturing I/O data for diagnostic logging and sequence control.

Process and machine-level data reach the controller through PROFIBUS-DP, which uses an EIA-RS485 physical layer and connects through a female D-Sub 9 connector; an onboard repeater can source up to 75 mA for the segment. A secondary RS-232 port is available for point-to-point service access. On the local side, the unit provides 11 digital inputs with a 24 V switching level and 4 digital outputs that can each deliver up to 0.5 A. Common logic lines are supplied through the X31/X32 terminals, where the board accepts a maximum draw of 1.1 A from a 24 V DC I/O supply. A normally open relay contact supports signaling loads up to 24 VDC at 1 A without using the transistor outputs.

Feedback and analog resources are handled separately. Two analog channels can source a 5 V analog output with up to 1 mA output current, which is useful for speed reference or valve control. Encoder cabling connects through a D-Sub 15 connector that supports incremental 1 Vpp, 5 V TTL, or the EnDat 2.1 bidirectional protocol, and the port supplies 5 V DC at 350 mA to power the sensor. The controller’s safety section follows the Safe Motion (S2) profile and is powered through the X41 supply at 24 V DC with 1.6 A available. Its dedicated channel can switch 0.5 A to downstream safe relays without sharing the standard I/O bus.
