Brief introduction:

Advantech ADAM-6066 is a 6-channel Modbus TCP digital input expansion module, supporting 6 channels of Relay output.

Through internet technology, ADAM-6066 integrates automation and enterprise systems easily without having to change the entire architecture of the control system.

This compact module works as a stand-alone instrument for measurement, control and automation thanks to the integrated intelligent control via Peer-to-Peer network and the graphical function GCL (Graphic Condition Logic) ) without the need for additional controllers or programming.

Supporting multiple protocols Modbus/TCP, TCP/IP, UDP, HTTP, DHCP, SNMP, MQTT Comes with industry standard design, ADAM-6066 is suitable for many industrial IoT applications.
