Product Description:

The CSH01.1C-SE-EN1-EN1-NNN-NN-S-NN-FW is a single-axis control card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It installs in IndraDrive power sections and coordinates servo loops, fieldbus traffic, and machine-level safety interlocks in automated equipment. By translating motion commands into time-synchronized drive signals, the board links higher-level PLCs to motors and sensors so that conveyors, pick-and-place arms, and processing stations follow precise velocity and position profiles.

The card’s analog feedback port is rated at ±10 V / 160 kΩ, allowing differential process variables to be read without placing a heavy load on the upstream transducer. SERCOS optical fiber provides deterministic control communication, and the interface uses SERCOS II. Discrete field wiring enters through digital inputs rated for 24 V / 3 mA, while the base logic and LED indicators draw only 7.5 W from the internal 24 V supply. A dedicated EN1 encoder extension consumes an additional 6 W when resolver or high-speed feedback devices are connected. Both encoder channels accept resolver or HSF signals, and their excitation drive is generated on the board at 18.2 Vpp AC. During power-up, filter capacitors charge with an inrush current of 4 A, and edge-triggered probes can capture state changes down to a maximum pulse width of 100 ms.

An analog output rated at 5 V / 1 mA is provided for tachometer feedback or torque reference signals. Four transistor outputs can source up to 24 V / 0.5 A to drive contactors or indicator lamps, and the resolver excitation frequency is held at 4 kHz for stable position tracking. The probe input responds within 1 µs, which supports tight synchronization with fast machine cycles. Relay contacts on the board are suitable for DC 24 V / 1 A loads, and the module is not equipped with integrated safety technology, so any SIL-rated functions must remain in the external control architecture.
