Product Description:
The CDB02.1B-ET-EC-EC-EC-L3-L3-EM-NN-FW belongs to the CDB Control Units series manufactured by Bosch Rexroth Indramat. Within a modular drive system, this plug-in control card manages motion commands, feedback data, fieldbus traffic, and safety interlocks for servo and induction axes. By concentrating signal processing on the board, the associated power section can focus on current modulation while the machine PLC receives a clean Ethernet or encoder data stream for deterministic automation tasks.
Network interfacing is handled through a Multi-Ethernet port that supports 100Base-TX signaling over an RJ-45, 8-pin connector, allowing direct attachment to standard industrial switches. Discrete control is extensive: the board provides 14 digital inputs for limit switches or sensors and 8 configurable I/O points that can be assigned as additional inputs or outputs according to project needs. Each output line can source up to 500 mA of digital output current, enough to drive contactors or indicator lamps without relays. For functional safety, the hardware integrates 2 Safe Torque Off channels; when both are de-energized, the drive power stage is reliably disabled to avoid unintended motion. A dedicated encoder supply offers 500 mA at 5 V while the total encoder power budget stays within 6 W, protecting feedback devices from overload.
Position feedback flexibility is expanded by 3 multi-encoder interfaces that accept incremental, EnDat, or the SSI absolute emulation format. Four probe inputs allow precise capture of edge-triggered position events, and the card reserves 4 optional slots for future fieldbus or memory extensions. Two analog voltage inputs and two outputs support velocity or pressure loops, and the outputs resolve commands at a granularity of 24 mV per increment so fine adjustments reach the drive without dithering. Analog stages share the same reference as the encoder supply, and the inputs tolerate the full ±10 V swing, giving the control system consistent scaling across every signal path.
