Product Description:

The CDB01.1C-PB-ENS-ENS-NNN-MA1-NN-S-NN-FW belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. It is a dual-axis control card used inside IndraDrive power sections to coordinate motion commands, accept encoder feedback, and forward status data to higher-level PLCs. By combining analog I/O, fieldbus communication, and integrated encoder supplies, the card provides a compact interface between drive hardware and the broader automation network.

This control unit communicates with the host controller through PROFIBUS-DP, allowing real-time parameter changes and diagnostics over a deterministic bus. Two differential analog inputs and two voltage outputs use 12 bit conversion, giving 4096 discrete steps for setpoint or feedback scaling. Each output can swing across a programmable window that centers on a baseline of 5 V and spans the full ±10 V range, enabling direct connection to industry-standard process transmitters. Internally, the board handles two motion axes and evaluates fast position latches through a TTL counter that accepts edge rates up to 400 kHz. For incremental or serial encoders, the input stage terminates the line with 120 Ω, matching typical transmission impedance and minimizing reflections on long motor cables.

The card supplies transducers directly so that no external power source is necessary. Its encoder header delivers 11.6 V DC at up to 500 mA, while the grouped digital outputs can source a combined 1000 mA with an individual channel limit for each output. Dry contact relays mounted on the board can switch inductive or resistive loads drawing up to 1 A, and their 30 V DC rating is adequate for most low-voltage actuator coils. The available current capacity and onboard relay circuitry allow sensors, brakes, and signal lamps to be powered and controlled directly from the drive cabinet without auxiliary terminals.
