The F3LH01-1N is a YHLS (Yokogawa High-speed Link System) master module used for remote I/O in Yokogawa’s FA-M3 programmable logic controller (PLC) system. Its purpose is to serve as a communication hub between a CPU module and multiple slave I/O units, enabling fast, reliable digital signaling over distances with many I/O points. It supports standard FA-M3 base mounting, connects via European-type connectors and is built to industrial environmental standards.
