Product Description:

The CDB01.1C-PB-NNN-NNN-NNN-NNN-NN-S-NN-FW is a plug-in control section produced by Bosch Rexroth Indramat for the CDB Control Units series. The module functions as the central processor inside Rexroth drive controllers, directing feedback handling, motion commands, and machine signal exchange for two axes of motion. By combining local I/O conditioning with a PROFIBUS fieldbus channel, the unit links servo drives to higher-level PLCs and SCADA systems, enabling deterministic command execution within automated production cells. It is suited to applications where drive control and machine-level signal exchange need to remain in one compact control platform.

Each analog command channel presents an input resistance of 160 kOhm, minimizing sensor loading, while the output stage resolves setpoints in increments of 19.5 mV/inc. The board supervises 2 axes and feeds the local 24 V logic rail with up to 1.1 A for connected limit switches, light curtains, or contactors. Communication with the machine controller runs on PROFIBUS at up to 12 MBaud, supporting fast cyclic data exchange. Discrete inputs register an OFF state when voltage falls below the 5 V threshold and switch ON once 15 V is reached, which helps reject noise-induced transients. At initial energization, the card draws 6 A of inrush for 60 ms before settling to a continuous power consumption of 11 W.

Output circuitry is arranged in two groups, and each group can deliver 1000 mA cumulatively, with a ceiling of 500 mA per individual channel, allowing direct actuation of small solenoids or stack lights. The high-speed probe input accepts position latches with a 4 µs pulse width, which helps motion capture align closely with external markers. Integrated relay contacts are rated for 1 A at up to 30 V DC, providing galvanically isolated switching paths for brake release valves or contactor coils. When the supply drops beneath the 5 V turn-off level, the module disables outputs quickly so driven actuators return to a defined state. This behavior supports orderly signal handling during undervoltage conditions.
