1. Overview

Y311-660 is a 6DI + 6DO remote I/O module available in two network variants.

Model	DI	DO	Connectivity	Typical Applications
Y311-660-W	6	6	2.4 GHz Wi-Fi, AP/STA	Remote pumps and valves, lighting control, power status feedback
Y311-660-R	6	6	10/100M RJ45 Ethernet	Remote pumps and valves, lighting control, power status feedback

Both models share the same I/O specification and control logic. The only major difference is the network interface.
