Product Description:

The CSH01.1C-PB-ENS-EN1-MA1-NN-S-NN-FW is an automation controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It operates as the central processing unit for drive-based motion systems, coordinating command, feedback, and fieldbus traffic between servo inverters and higher-level PLCs. By executing real-time logic, it links discrete I/O, analog process signals, and network data so that connected axes follow programmed profiles with deterministic timing.

The module draws a base power consumption of 7.5 W, limiting heat generation inside compact cabinets. Each digital input turns on at 15 V, and the sourcing digital outputs can deliver up to 500 mA, allowing direct actuation of relay coils or indicator lamps. Motion and process feedback enter through the MA1 board, which offers two analog inputs and two analog outputs; the outputs are scaled in 19.5 mV increments while the inputs are digitized to 12-bit resolution for consistent control accuracy. Network coupling is handled through a fieldbus port that supports PROFIBUS-DP telegrams at a maximum bus speed of 12 MBaud, enabling high-density node installations without cycle-time penalties.

Internal sensor supplies are provided on two rails: 8 VDC for EN1 high-speed feedback devices and 11.6 VDC for ENS encoder evaluation, so external power packs are unnecessary for most transducers. A form-C relay rated at 24 VDC and 1 A offers galvanically isolated signaling to safety interlocks, although the controller itself does not include dedicated safety technology. Point-to-point diagnostics use the RS232 interface, and diagnostic or trace data can move across the link at up to 115 kBaud. The analog section also allows the controller to exchange reference and monitoring signals with external devices, which helps coordinate mixed-signal applications from a single platform.
