Produktinformationen "U-7502M OPC UA I/O Module with PoE, 3 AI, 6 DI and 3 Relay Outputs"
U-7502M CR is a remote I/O unit that brings analogue, digital and relay channels onto an Ethernet network and makes them available to OPC UA, MQTT and RESTful API clients. It suits engineers who need to feed field I/O values into a cloud platform or a higher-level control system without adding a separate gateway.
The module can run OPC UA Server or Client, MQTT Client and RESTful API communication at the same time, so the networking approach can be chosen to suit each installation. Local logic is handled by IF, THEN, ELSE rules that can act on physical and virtual points, and a schedule function executes rules at set times. Analogue inputs can be scaled into more readable engineering values, and I/O trigger messages can be written to CSV files or a line for device tracking.
Power can be taken from a PoE network under IEEE 802.3af Class 3 or from a +12 to +48 VDC terminal block. A dual-port Ethernet switch supports daisy-chain topology to reduce cabling and switch requirements. Configuration, control and monitoring are done through the built-in web interface in a standard browser, with no additional app required.
Applications
- Transmitting I/O values to cloud systems for display, analysis or strategy
- Feeding field I/O data into a control system over OPC UA or MQTT
- Remote monitoring and control of I/O via a web browser or RESTful API
- Local rule-based automation of I/O and virtual points on a schedule
- Installations where PoE power and daisy-chained Ethernet reduce cabling
