Features
- • Built-in Web Server to Provide the Web User Interface
• Built-in OPC UA Server
• Support MQTT Client Communication Protocol
• Support Scaling
• Built-in I/O Channels (4 x DI, 4 x AI, and 4 x AO)
• 2-port Ethernet Switch for Daisy-Chain Topology
• IEEE 802.3af-compliant Power over Ethernet (PoE)
Introduction
A-7504M is a UA I/O module that provides 4 digital input channels, 4 analog input channels and 4 analog output. 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.
UA-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 wirings and power sockets.
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. Support Scaling. Let the analog signal be converted into a more readable value.
