4 port 10/100M Network Switch with 2 relay output IO controller

1. General Introduction

WS-4E2K2-IO2 is a high performance and good price IOT network controller. The device integrated 4 channel TCP/IP communication ports with 2 channel of input/output interface all in one. Its 4 ports 10M/100M RJ45 Ethernet interface for TCP/IP network switch, plug and play; two channel input interface support dry connector input (from DC5V to 0V). 2 channel of relay output max control of AC105V to AC250V (10A) equipment. We provide free protocol and testing tools for your 2nd software development. The device can use for many applications such as remote power supply control, access control, automatic gate control, etc.
