Product Description:

The CSH01.1C-PB-ENS-EN1-EN2-S1-S-NN-FW motion-logic control card is supplied by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive drive stack, it becomes the command layer that schedules motion profiles, evaluates encoder signals, and exchanges process data for coordinated multi-axis machinery. By combining probe capture, encoder power supplies, and dedicated safety terminals on one board, it streamlines cabinet layouts in automated assembly lines, packaging cells, and material-handling systems.

The board links to higher-level PLCs over PROFIBUS-DP through a D-Sub 9-pin female port, so cyclic setpoints and diagnostics are delivered on the same fieldbus. The two differential analog inputs each have an input resistance of 160 kΩ, minimizing loading on external sensors. Eight transistor outputs are rated for 0.5 A each, while the common I/O supply can furnish 1.1 A to peripheral devices. The primary encoder interface (EN1) provides DC 8 V / AC 18.2 Vpp excitation for SinCos or TTL feedback, ensuring clean signal amplitude even on long motor cables. A fast probe channel supports registration tasks with edge-to-edge accuracy of 1 µs, a 4 µs minimum pulse width, and clean switching between 15 V on-level and 5 V off-level, allowing precise product tracking on high-speed conveyors.

The secondary encoder port (EN2) supplies 5.0 V DC at up to 350 mA and accepts incremental inputs that must present a terminating load of 35 Ω, enabling direct connection of digital linear scales. An auxiliary ENS output delivers 12 V for external position sensors that require more than low-level signal power. A form-C relay is available for ready-signal forwarding and is rated at 24 V DC, 1 A, giving galvanic isolation to safety circuits. Integrated Safety technology I/O lets the controller participate in emergency-stop chains without extra hardware, so the system can support Category 3 and Performance Level d functional safety targets while keeping the drive layout compact.
