Technical Specifications Model: NOCR‑01C Part Number: 3AFE64300245 Communication Protocol: DDCS Optical Interface: One input optical port, one output optical port Communication Rate: 10 MBd Power Supply: 24 VDC ±10 % Mounting Method: 35 mm DIN‑rail mounting Operating Temperature: ‑10 ℃ to +55 ℃ Storage Temperature: ‑25 ℃ to +70 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Completes DDCS optical‑signal receiving, reshaping and regeneration to extend optical‑bus transmission distance. Bidirectional signal regeneration for DDCS bus communication. Compensates optical‑signal attenuation brought by long‑distance optical‑cable transmission. LED indicators display input and output optical‑signal status. DIN‑rail modular structure for convenient installation inside control cabinet. On‑board self‑diagnosis monitors power‑supply abnormality and input optical‑signal loss.
Application Scenarios Spare‑part replacement for NOCR‑01C 3AFE64300245 DDCS repeater in ABB multidrive system. Long‑distance DDCS optical‑bus communication for distributed‑layout multidrive equipment. Signal‑attenuation compensation for long‑cable DDCS communication link of chemical plant and paper‑making machine drive system.
Installation Requirements Clip NOCR‑01C onto 35 mm standard DIN‑rail inside cabinet, maintain horizontal installation orientation. Complete 24 VDC power‑supply wiring at screw‑type terminal block. Connect upstream optical‑bus cable to input optical port, connect downstream optical‑bus cable to output optical port. Reserve heat‑dissipation clearance around module, do not block housing ventilation openings. Ambient operating temperature shall maintain within ‑10 ℃ ~ +55 ℃ without condensation. Verify upstream‑downstream DDCS‑bus communication function after power‑on.
