Product Description:

The CSH01.1C-S3-ENS-NNN-MEM-S2-S-XP-FW is a controller board produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive racks, the board handles axis logic, fieldbus communication, and integrated safety functions that coordinate servo drives and peripheral I/O in automated machinery. By using an interchangeable memory card, it stores motion data and operating parameters on removable media.

Its analog output section delivers a resolution of 19.5 mV/inc, providing fine reference signals to amplifiers that rely on voltage control loops. Logic electronics and encoder interfaces operate from a backplane supply of DC 24 V, while the base board dissipates only 7.5 W, minimizing cabinet heat. During power-up, the capacitors draw 4 A of inrush current, so line fusing must tolerate that surge. Digital outputs can source 500 mA per channel, and their timing is limited to a 100 ms pulse width, ensuring deterministic state changes during safety sequences. The ENS interface presents 120 ohms of input impedance and can supply 500 mA at 11.6 V to external sensors, creating a dedicated enable path without overloading the control rail.

For high-speed data exchange, the MEM channel supports differential lines up to 40 m and streams position updates at 1 MHz, matching the cycle rates demanded by modern interpolation functions. Network connectivity is provided through a Sercos III port that follows the 100Base-TX standard and accepts copper cables to a maximum length of 100 m, allowing the controller to sit remotely from distributed drives. Auxiliary diagnostics are available through the integrated RS-232 port, where parameters can be edited at up to 115 kBaud. A form-C relay rated for 1 A and a safe-motion I/O header delivering 1.6 A support low-voltage switching functions for brakes, contactors, or external gate circuits.
