Why the NU series cuts wiring and installation time
Open field networking for FS-N series amplifiers (per KEYENCE official materials):
- Single cable to your PC/PLC - only one communication cable is needed between the PC/PLC and the NU series, drastically reducing wiring and installation time
- Remote management - read measurement data and rewrite amplifier settings from the PLC side, improving convenience and cutting changeover work
- EtherCAT ready: cyclic (process data object) and mailbox (message) communication, CoE compatible, dual RJ-45 ports for daisy-chaining at 100 Mbps
- Powers your amplifiers: the NU-EC1 feeds 24 VDC to the connected N-bus amplifiers through the wiring-saving connector (total 1,200 mA or less) - up to 16 units in one group
Family note: The NU series links N-bus sensor amplifiers (such as the FS-N series) to your PC/PLC with a single communication cable - drastically cutting wiring and installation time, with remote management of amplifier settings for better convenience. This listing is the EtherCAT model NU-EC1; the family also includes NU-EP1 (EtherNet/IP), NU-EC1 (EtherCAT) and NU-DN1 (DeviceNet).
FAQ
Q: Which amplifiers can the NU-EC1 connect to?
A: Sensor amplifiers with N-bus support - in practice the KEYENCE FS-N series digital fiber optic amplifiers. Up to 16 units can be linked in one group (varies with the amplifiers used).
Q: Does the NU-EC1 power the amplifiers?
A: Yes - the unit supplies 24 VDC +/-10% to the connected N-bus amplifiers through the wiring-saving connector (total passing current 1,200 mA or less), so the amplifier group needs no separate power wiring.
Q: What is the lead time for the NU-EC1?
A: This is a genuine unit sourced to order. Lead time is confirmed at quotation, typically 1-3 weeks, and every unit is inspected before shipment.
Typical applications
- EtherCAT networking for FS-N series amplifiers, single communication cable between PC/PLC and the NU unit, remote centralized monitoring and setting management
