Brief introduction:

ADAM-6250 is a Modbus TCP module providing 8 digital input channels, 7 digital output channels, integrated with 2 additional 10/100 Base-TX Ethernet ports.

Powered by Peer-to-Peer (P2P) networking and Graphic Conditional Logic graphics, the ADAM-6250 can function as a stand-alone device for measurement, control and automation.

Through internet technology, this compact module can be monitored and controlled remotely with mobile devices. In addition, ADAM-6250 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 XML, HTML5, Javascript, ADAM-6250 web language is considered as an I/O solution integrated in the Ethernet control system.
