Specification

The Keyence NU-EP1 is a high-performance communication unit engineered for seamless integration into EtherNet/IP networks. As part of the Keyence network communication series including NU-EC1, NU-DN1, NU-CL1, and NU-EN8N, the NU-EP1 excels in bridging sensor amplifiers to industrial Ethernet systems. It supports both 10BASE-T and 100BASE-TX standards, ensuring compatibility with legacy and modern infrastructure. With PoE (Power over Ethernet) Class 3 capability, it eliminates the need for separate power lines, while the N-bus interface allows direct connection of up to 16 sensor amplifiers. This unit is ideal for applications demanding high-speed cyclic communication, robust message handling, and reliable power distribution in harsh factory environments.
