U-7504M OPC UA I/O Module with 4-ch DI, 4-ch AI, 4-ch AO & 2-port Ethernet Switch


Key Features

  • Built-in Web Server to Provide the Web User Interface
  • Built-in OPC UA Server
  • Support MQTT Client Communication Protocol
  • Built-in I/O Channels ( 4-ch DI, 4-ch AI & 4-ch AO)
  • 2-port Ethernet Switch for Daisy-Chain Topology
  • IEEE 802.3af-compliant Power over Ethernet (PoE)


The ICP DAS U-7504M is an OPC UA I/O module that provides 4 digital input, 4 analog input, and 4 analog output channels. It has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easier and total costs of cable and switch are significantly reduced. The ICP DAS U-7504M follows IEEE 802.3af compliant Power over Ethernet (PoE) specification. It allows receiving power from PoE enabled network by Ethernet pairs. This feature provides greater flexibility and efficiency to simplify system design, save space, and reduce wiring and power sockets. It provides a Web UI to configure/control/monitor the modules, connections, and I/O status via a web browser. It is easy, fast, and no extra APP needed.

ICP DAS UA I/O provides OPC UA server and MQTT client function in industrial networking communication. Users can choose the networking mode according to their needs and environment, to transmit the values of built-in I/O channels to the cloud IT system or field control system for reading and writing. This unit support scaling to convert the analog signal into a more readable value.
