Brief introduction:

ADAM-6256 is a Modbus TCP module that provides 16 isolated digital output channels, integrated with 2 additional 10/100 Base-TX Ethernet ports.

Powered by Peer-to-Peer (P2P) network and Graphic Conditional Logic graphics, ADAM-6256 can work as a stand-alone device for measurement, control and automation, monitoring and remote control away from mobile devices. In addition, this compact module also has the ability to configure groups to set up many other modules.

Industry standard design, support for multiple protocols Modbus/TCP, TCP/IP, UDP, HTTP, DHCP, SNMP, MQTT and web language XML, HTML5, Javascript, ADAM-6256 applied as an I/ O integrated in the Ethernet control system.
