Product Description:

The CDB01.1C-SE-EN2-EN2-NNN-NNN-S1-S-NN-FW is a plug-in control section manufactured by Bosch Rexroth Indramat for the CDB Control Units series. Installed on compatible power modules, it handles motion commands, feedback processing, and safety monitoring for industrial servo axes. Its role in an automation cabinet is to translate network telegrams into drive-level signals while coordinating encoder data and digital I/O, so the system can react to commands and feedback within the same compact hardware footprint.

This control section draws a base power of 9 W, so its internal electronics add only a minor thermal load inside the enclosure during operation. Command exchange with the host PLC uses the SERCOS II fiber-optic ring, providing deterministic timing for multi-axis synchronization. Operators interact through a standard control panel that plugs onto the front card edge. The board supports an encoder interface count of 2, and both channels use EnDat 2.1 / 1 Vpp / 5 V TTL signals for feedback. Each channel supplies 5.0 V at 350 mA and uses a 35 Ω load resistance to help prevent overcurrent faults. For actuator signaling, the card sources up to 500 mA per digital output, which is suitable for small relays or optocouplers.

Total sourcing capability over one output group is 1000 mA, allowing several devices to be powered at the same time without an external supply. On start-up, the circuitry can tolerate an inrush of 6 A before settling to steady-state draw. Pulse-shaped commands generated by the safety logic are limited to a maximum width of 60 ms to meet category timing tests. Safe shutdown and enabling are routed through an X41 D-Sub 9 connector that carries Safety Technology I/O, with channel inputs rated at 24 V / 3 mA and feedback outputs rated at 24 V / 0.5 A to drive contactors or status lamps without auxiliary interface boards.
