The NU-CL1 from Keyence integrates N-bus sensor amplifiers into a CC-Link network. This unit acts as a remote device station. It reduces wiring work significantly because one communication cable handles data transmission to the PLC. Furthermore, the module supplies power to connected amplifiers directly through a wiring-saving connector. Therefore, engineers can deploy compact sensor networks without complex parallel wiring.
The CC-Link interface supports Ver.2.00 and Ver.1.10 with switchable operation. Transmission speeds range from 156 kbps to 10 Mbps across five selectable steps. Station numbers are configurable from 1 to 64. In Ver.2.00 mode, the unit occupies 3 stations. Meanwhile, Ver.1.10 mode allows selection of 1, 2, 3, or 4 occupied stations.
Sensor connectivity is a core feature. The NU-CL1 accepts up to 16 N-bus compatible sensor amplifiers. Moreover, the allowable passing current totals 1,200 mA or less for the connected amplifier chain. This capacity supports multiple sensor types, including fiber, photoelectric, laser, pressure, and flow amplifiers. The unit supplies power to these amplifiers via the wiring-saving connector, eliminating separate power runs to each sensor position.

CC-Link Communication Parameters
Supported Version: Ver.2.00 / Ver.1.10 (switchable)
Station Type: Remote device station
Occupied Stations: Ver.2.00 = 3 stations; Ver.1.10 = 1/2/3/4 stations (switchable)
Transmission Speed: 156 k / 625 k / 2.5 M / 5 M / 10 Mbps

The unit weighs approximately 0.08 kg including connectors. Its compact housing suits tight cabinet spaces and distributed sensor junction boxes. Operating temperature ranges from -20 to +55 °C without freezing. Relative humidity must stay between 35 and 85% RH with no condensation. The NU-CL1 is designed for standard industrial environments where CC-Link networks are common.
First, mount the NU-CL1 on a DIN rail or flat panel inside the control cabinet. Next, connect the CC-Link terminal block to the network cable. The unit includes a CC-Link connector and power connector in the package. Then, set the station number and transmission speed using the rotary switches on the front face. After that, connect the N-bus sensor amplifiers using the wiring-saving connector. Finally, apply 24 VDC power and verify the CC-Link LED indicators for normal operation.
Ensure the total current draw of all connected sensor amplifiers stays below 1,200 mA. Additionally, terminate the CC-Link network properly using the supplied 110 Ω, 1/2 W terminal resistors. The unit supports both Ver.2.00 and Ver.1.10 networks; therefore, confirm the master station's version before powering up.
