Product Description:

The CDB01.1C-ET-ENS-ENS-NNN-NNN-NN-S-NN-FW belongs to the CDB Control Units series produced by Bosch Rexroth Indramat. Mounted on an IndraDrive system, this control unit coordinates input, output, and feedback channels so that connected servo or spindle drives follow motion commands issued by a supervisory PLC. It supports Multi-Ethernet transport layers and supplies the signal conditioning required for analog process values and 24 VDC machine wiring. The device is installed where compact drive-level intelligence is preferred over separate remote I/O modules.

The analog front end presents an input impedance of 160 kΩ; this high value minimizes loading on external transducers tied to the ±10 V differential range accepted by each channel. Outgoing reference loops are available as sourcing drivers that can supply 1 mA at up to 5 V, enabling speed or torque setpoints to be delivered directly to legacy drives. For networked applications, the integrated MultiEthernet interface handles real-time messaging without an additional communication card. Digital control lines draw only 3 mA per input at 24 V, while transistor outputs can switch 0.5 A for solenoids or contactors. During power-up the module withstands an inrush of 6 A for 60 ms, after which steady-state electronics operate from the internal 24 V bus.

Total control electronics consumption is rated at 23.2 W, a figure useful when sizing the auxiliary supply rail for multi-axis systems. The enclosure measures 103 mm deep, 49.5 mm wide, and 322.6 mm high, allowing several units to be stacked densely on a drive stack without exceeding typical cabinet depths. Across all 16 digital inputs, the current demand remains modest, which helps ease power budgeting. The high-side outputs can actuate relays or small pneumatic valves directly without an intermediate interface relay.
