Description
Brief introduction:
ADAM-6251 is a Modbus TCP module that provides 16 digital input 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-6251 can function as a stand-alone instrument for measurement, control and automation, as well as configurability. group to set up many other modules.
Through internet technology, this compact module can also monitor and remotely control mobile devices.
Industry standard design, support for multiple protocols Modbus/TCP, TCP/IP, UDP, HTTP, DHCP, SNMP, MQTT and XML, HTML5, Javascript, ADAM-6251 web language as an I/O solution integrated in the Ethernet control system.
