Product Description:

The CSH01.1C-ET-EN2-NNN-MEM-S2-S-NN-FW control unit belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It is a compact automation controller designed to process motion commands, fieldbus traffic, and local safety signals for multi-axis drive systems. By combining real-time CPU resources with modular interface slots, the device acts as the central coordinator between servo inverters, supervisory PLCs, and factory networks, ensuring synchronized positioning and deterministic cycle times on assembly lines and packaging machinery.

In base operation, the controller draws 7.5 W, so heat generation inside a sealed cabinet stays low. Communications to higher-level networks are handled through the 100Base-TX (IEEE 802.3u) port, while legacy equipment can be connected on the RS232 serial interface. The configurable analog channel sources 5 V / 1 mA, allowing direct transmission of reference values to external sensors or drives. For internal add-on cards, the En2 encoder interface requires 6 W, providing stabilized 5 V excitation to incremental encoders. A single-line display on the front panel offers menu navigation without an external programming terminal.

For motion blocks stored on the MEM option, the Et communication card consumes 2.2 W and supports a maximum cable length of 40 m between the controller and remote modules. Position latch events can be captured at a burst rate of 1 MHz, and persistent parameters reside on a MultiMediaCard for retained storage. The integrated relay output is rated at DC 24 V / 1 A for direct actuator control, while the safety input accepts 24 V at 3 mA and the safety output sources 24 V at 0.5 A through a D-Sub 9-pin female connector. A separate MEM module draws 2 W, and the encoder supply maintains a steady 5 V to support noise-immune position feedback.
