Brief introduction:

ADAM-6266 is a Modbus TCP module that provides 4 Relay output channels, 4 digital input channels, and 2 additional 10/100 Base-TX Ethernet ports.

Powered by Peer-to-Peer networking and Graphic Conditional Logic graphics, the ADAM-6266 can work as a standalone device for remote monitoring and control with mobile devices.

In addition, this compact module of only 70x122x27mm has the ability to configure groups to set up many other modules.

Industry standard design, support multiple protocols Modbus/TCP, TCP/IP, UDP, HTTP, DHCP, SNMP, MQTT and web language XML, HTML5, Javascript, ADAM-6266 is applied as an I/ O integrated in the Ethernet control system.
