Product Description:

The CDB01.1C-PB-ENS-ENS-NNN-MEM-S1-S-NN-FW is a plug-in control section from Bosch Rexroth Indramat that belongs to the CDB Control Units series. Mounted on an IndraDrive power module, it converts high-level PLC instructions into drive setpoints while also managing status feedback. In automated production cells, the unit coordinates multiple servo axes, safety enable signals, and onboard I/O, making it a central element for precise, synchronized motion control. Its hardware profile includes dedicated PROFIBUS and encoder slots, a memory expansion bay, and a 24 V service supply so the drive can keep critical logic alive during mains removal.

Central fieldbus traffic is handled by the integrated PROFIBUS-DP interface. This port is presented on a 9-pin female D-Sub connector and transmits cyclic process data at up to 12 MBaud, allowing fast synchronization with PLC masters. The digital output block can source 500 mA, which is adequate for small contactors or indicator lamps, while the grouped supply rail supports 1000 mA for concurrent switching tasks. Two enable channels monitor safety relays, and each input has a resistance of 120 ohms with an internal supply of 11.6 V for reliable edge detection over long cable paths. For rapid latch signals, the memory module offers a maximum output frequency of 1 MHz, which suits position-capture applications such as registration marks on packaging machines.

Auxiliary serial access is available through an RS-232 maintenance socket. The Mini-DIN 8-pin female connector supports distances of up to 15 m and transfer rates up to 115 kBaud, making it suitable for parameter backups without loading the fieldbus. The S1 extension channel supplies a maximum of 1.6 A at 24 V. Within that operating range, its protected transistor output is rated for 24 V at 0.5 A, so discrete sensors or interlock coils can be powered directly. Memory functions remain stable with cable runs to 40 m, and the onboard relay pair can switch DC 24 V at 1 A for peripheral alarms.
