Product Description:

The CSH01.1C-NN-ENS-MA1-MD1-S1-S-NN-FW is a controller module from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It is installed in drive-based automation assemblies where it coordinates local I/O, encoder feedback, and motion commands, allowing the larger system to execute precise positioning and sequencing tasks. It links machine signals with motion functions, so changes at sensors and switches can be processed close to the drive. The input stage accepts encoder signals from incremental IndraDyn, HIPERFACE, and 1 Vpp devices, which allows the module to work with several common servo motor feedback formats.

This module provides 2 additional analog input channels for process variables such as pressure or temperature and 12 additional digital inputs for on/off signals from sensors or limit switches. All circuitry is powered from a DC 24 V control supply that must be available continuously from the cabinet power rail. At power-up, the unit draws a typical inrush current of 4 A for up to 100 ms before settling to its 7.5 W power consumption during normal operation. Encoder reference signals are supplied by an 11.6 V output rated at 300 mA, which allows connected transducers to receive regulated power directly from the module without a separate low-power source.

The module also includes 2 additional analog output channels for actuator setpoints and 8 additional digital outputs for relay or coil control. Each analog channel uses a 12 bit converter, which provides fine resolution when scaling voltage or current commands for external devices. Communication with higher-level PLCs or diagnostic tools is available through an RS232 serial interface, supporting direct serial access when needed. During encoder initialization, the board limits its supply surge to a 100 ms pulse width to reduce the chance of brownouts on the shared control bus.
