Product Description:

The CSH01.1C-SE-EMS-NNN-NNN-S1-S-NN-FW is an automation controller module manufactured by Bosch Rexroth Indramat in the CSH Advanced Controllers series. Intended as the processing core of IndraDrive systems, it coordinates motion axes, manages field communication, and supervises integrated safety channels within an industrial cell. By governing a SERCOS network and a serial service link, the unit bridges higher-level PLC commands with drive-level feedback to maintain deterministic motion sequences on production lines.

The controller interfaces directly with external sensors and actuators. Each analog input presents 160 kOhm of resistance, minimizing load on precision transducers, while the analog output stage sources up to 1 mA into loads of at least 5 kOhm to keep reference levels stable. Four configurable digital I/O points and five dedicated digital inputs provide direct binary interaction, and sourcing outputs can deliver 0.5 A per channel for relay coils or solenoids. Master communication is managed on the SERCOS optical ring, and 2 W of internal power is reserved for that bus. Safety I/O hardware embedded on the card allows emergency stop circuits without additional external relays.

During startup, the module draws a typical inrush of 4 A and sustains that surge for a maximum of 100 ms before settling to a base demand of 7.5 W at the 24 V supply rail. On-board relays can switch field loads up to 24 VDC at 1 A, supporting contactors or status beacons. Two shared analog and digital inputs accommodate mixed-signal tasks such as monitoring temperature while capturing edge triggers. Long-distance diagnostics are available through the built-in RS232 port, permitting parameter uploads without interrupting the SERCOS ring. The short inrush period affects upstream supply selection and fuse coordination.
