Product Description:

The CDB01.1C-S3-NNN-NNN-NNN-NNN-L1-S-NN-FW control unit is produced by Bosch Rexroth Indramat and belongs to the CDB Control Units series. It is installed in drive cabinets to translate field-level commands into precise drive actions, manage local I/O, and apply integrated safety logic to industrial axes and auxiliary equipment. It also coordinates command transfer between higher-level control functions and the connected drive hardware during normal machine operation. It supports coordinated motion tasks where communication timing and local signal handling must remain consistent across the machine cycle. By combining master communication, signal conditioning, and relay functions, it provides a compact supervisory layer for automated machinery.

The module accepts an analog reference span of ±10 V and reports processing status through 22 digital inputs that are sensed at 24 V DC with a 3 mA nominal load for straightforward connection to common control signals. Physical dimensions are fixed at a height of 322.6 mm, a width of 49.5 mm, and a depth of 103 mm, so panel space allocation is straightforward. Master communication runs over SERCOS III, and two independent fiber rings terminate on 2 x RJ45 ports for deterministic cyclic data exchange. For internal logic commands, 4 configurable digital outputs are provided, each referenced to a 24 V DC bus that can deliver 0.5 A per channel.

An isolated analog monitor channel provides a calibrated output of 5 V / 1 mA, which is useful for drive diagnostics or external meters. The Ethernet service interface supports 10/100 Base-T connections for service access and parameter backup through standard network hardware. This connection is separate from the real-time control network, so routine access does not interfere with cyclic motion data. Control-side power enters through a relay block rated at 24 V DC / 1 A, and field discretes are switched by digital outputs at 24 V / 0.5 A for external signaling tasks. The safety architecture includes 6 A inrush management, Starting Lockout functionality, and Safety Stop Category 0, so motion is halted immediately when a stop is requested.
