4 Channel Ethernet Relay Module With IO Lan Wan Network RJ45 TCP IP Program Development Board Smart Home Open Source



General Introduction

WS-IO424TCP is a high performance and good price IOT network controller. It has 4 channel of input and output interfaces with a 10M/100M Ethernet RJ45 port can be compatible for correspondence of TCP/IP communication. It was developed to interface industry control area such as automatic light system, motor control, door access control, etc. The device is easy to be connected and can be remotely control by computer (include laptop, Raspberry Pi, Jetson nano,etc.) based on our free SDK. The controller working on DC9V to DC35V wide power supply, and the relay output can controlled of AC105V to AC250V (10A) equipment.
