Ethernet 2CH Relay RS232&RS485 IO module

WST-TCP2IO-212 is a high performance and good price IOT network controller. It has 2 channels of input and output interfaces with a 10M/100M Ethernet RJ45 port can be compatible for correspondence of TCP/IP communication. User can easily and quickly integrate WST-TCP2IO-212 into own system to realize remote, LAN and local control which based on Ethernet, RS485 and RS232. 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 DC24V wide power supply, and the relay output can be controlled of AC105V to AC250V (10A) equipment.
