Product Description:

The CSH01.1C-S3-ENS-NNN-NNN-NN-S-NN-FW is a single-axis controller card from the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. It slots into IndraDrive power sections to coordinate drive functions, gather field signals, and forward real-time status data to higher-level PLCs. By combining communication, encoder evaluation, and low-level I/O on one module, it serves as the interface between motion hardware and the plant network in industrial automation cells.

An analog input impedance of 160 kΩ minimizes loading on process transmitters, while the isolated analog output can source up to 1 mA for reference commands to external devices. Discrete actuators are handled through digital outputs rated at 24 V / 0.5 A, and limit switches or position sensors connect through the D-Sub 15 female encoder connector, which supplies 11.6 V at up to 500 mA. Drive and host exchange occurs on a front-mounted RJ-45, 8-pin port that supports Ethernet layer signaling at 100Base-TX, while time synchronization and parameter traffic follow the SERCOS III protocol. Power drawn by the dedicated ENS safety channel is 6 W, whereas the S3 logic section needs only 1 W, so thermal contribution inside the drive rack stays modest even under continuous operation.

During power-up, the card withstands an inrush of 4 A for a maximum of 100 ms, a profile that guides sizing of upstream fuses and supply wiring. High-speed position capture is assisted by probe circuitry that resolves events with 4 µs pulse width and maintains 1 µs timing accuracy, supporting camming or print-mark registration tasks. A form-C relay rated at DC 24 V / 1 A offers galvanically separated fault signaling to safety interlocks. The remaining I/O lets the controller manage encoder feedback, network traffic, and field devices without additional interface modules.
