Reliable Fiber Optic Communication Extension
The NTCF02 termination unit provides a fiber optic communication link for extending the Procontrol P14 and AC 800M systems over long distances. This termination unit converts electrical signals from the backplane into optical signals for transmission over multimode fiber cables. The unit supports both 62.5/125 μm and 50/125 μm fiber types, offering compatibility with standard industrial fiber installations.
Two ST connectors on the front panel provide the transmit (TX) and receive (RX) fiber connections. The unit achieves a maximum transmission distance of 2,000 meters, which greatly exceeds the limitations of traditional copper wiring. A data transfer rate of 2 MB/s ensures rapid and reliable communication between distributed control system components.
Signal Integrity and Noise Immunity
The NTCF02 termination unit eliminates the electrical noise and ground loop problems that commonly affect long copper cable runs. Fiber optic transmission provides complete galvanic isolation between connected devices, protecting sensitive control electronics from voltage surges and electromagnetic interference. This inherent immunity makes the unit particularly suitable for installations in high-voltage switchyards, large process plants, and electrically noisy factory environments.
Physical Design and Installation Features
This termination unit measures 67 mm in width, 130 mm in height, and 120 mm in depth, with a weight of 0.32 kg. The compact form factor fits easily within standard control cabinets. Users can mount the NTCF02 on a DIN rail or directly onto the backplane, providing installation flexibility for different panel layouts.
Two front-panel LEDs indicate data transmission activity: the green TXD LED flashes during signal transmission, while the yellow RXD LED illuminates upon receiving valid optical signals. Consequently, maintenance personnel can quickly verify communication status and diagnose link issues without specialized optical test equipment.
Power and Environmental Specifications
This termination unit draws 200 mA from the 5 VDC backplane, ensuring stable operation without additional power supplies. The NTCF02 operates reliably across a temperature range of 0°C to 60°C. It also withstands humidity from 5% to 95% (non-condensing) and resists vibration up to 2G at 10-150 Hz.
