ADAM-6217 8-ch Isolated Analog Input Modbus TCP Module

Download PDFDownload the ADAM-6217 data sheet.


ADAM-6217 ModuleThe ADAM-6217 features 8 analog inputs which can be individually configured for various current or voltage input ranges. The daisy-chained Ethernet ports simplify the wiring for multiple modules and eliminate the need for a dedicated port for each module.


  • Daisy chain connection with auto-bypass protection
  • Remote monitoring and control with smart phone/tablet
  • Group configuration capability for multiple module setup.
  • Flexible user-defined Modbus address
  • Intelligent control ability by Peer-to-peer and GCL function.
  • Multiple protocol support: Modbus TCP, TCP/IP, UDP, HTTP, DHCP, RESTful, SNMP and MQTT
  • Web language support: XML, HTML 5 and Java Script
  • System configuration backup
  • User Access Control
  • Easy mounting on DIN-rail, panel or piggyback
