Product Description:
The CDB02.1B-ET-EC-EC-EC-NN-NN-NN-NN-FW is a control section produced by Bosch Rexroth Indramat for the CDB Control Units series. Mounted next to a power stage, it supervises motion tasks, local I/O, and network traffic so that drive-based automation can be coordinated from a single board. Cabinet space is conserved because the housing combines fieldbus ports, analog conditioning, and user wiring blocks, which provides centralized diagnostics and shorter internal cable runs inside the control cabinet.
The unit communicates through a Multi-Ethernet interface, letting the same hardware operate on multiple industrial protocols without card changes. Its two analog outputs refresh every 750 µs, and each increment equals 24 mV/incr for fine voltage reference generation. The control section includes 2 analog voltage inputs for feedback devices such as potentiometers and 2 analog voltage outputs for external actuators. It also provides 14 digital inputs for fast edge detection, while four probe inputs capture position markers for synchronized machine events. Internal converters consume 1.1 W on the EC module and 2.7 W on the ET module, and a control supply monitor limits sourcing to 500 mA per output line to help protect connected sensors against overcurrent conditions.
Main logic is powered from a DC 24 V rail, and aggregate draw remains within 23 W, allowing dense installations on common power buses. Network wiring uses an RJ-45 8-pin connector that meets 100Base-TX signaling for deterministic exchange with higher-level PLCs. Four optional slots accept encoder, safety, or additional I/O cards, which expands the range of supported feedback and peripheral connections. Total sourcing capacity reaches 2000 mA when all outputs are active, so multiple field devices can be supplied from the control section. Two front-mounted Ethernet jacks keep communication ports accessible at the front of the module and support straightforward line integration in multi-axis machines.
