Product Description:
The CSH01.1C-NN-ENS-EN2-MEM-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Intended for use in IndraDrive power modules, the board serves as the local automation layer that converts sensor data into drive commands. It supervises axis position, velocity, and process I/O, which allows motion functions to be handled directly inside the drive rack. By combining analog, digital, and serial resources on one card, the module reduces external wiring and supports coordinated operation in packaging, printing, and assembly lines.
Five independent I/O blocks shape its electrical profile. Each differential analog input accepts ±10 V and presents an impedance of 160 kΩ, so load cells or potentiometers are not heavily loaded by the interface. A single analog output supplies reference levels up to 5 V / 1 mA. Discrete sensing is handled through inputs rated at 24 V / 3 mA, while outputs can switch solenoids or relays at 24 V / 0.5 A. No higher-level fieldbus is installed, and the RS232 interface is used for setup. The module has no integrated safety technology, so emergency stop and guard-monitoring functions must be handled by external circuitry.
The feedback side supports both primary and secondary encoders. A D-Sub 15 female connector feeds transducers with 12 V at up to 500 mA, while auxiliary rails provide 5 V for 1 Vpp, EnDat 2.1, or 5 V TTL devices. The module can output both absolute and incremental emulation formats, and this driver is galvanically isolated to block ground loops. Differential signal pairs may span 40 m without repeaters, which helps preserve stable encoder communication across larger machine layouts. This arrangement supports closed-loop positioning without adding separate control-cabinet hardware.
