Produktinformasjon "U-7555M OPC UA I/O Module, 8-ch DI, 8-ch DO and 2-port PoE Ethernet Switch"
The U-7555M is an Ethernet I/O module that brings 8 digital inputs and 8 digital outputs onto an OPC UA network. Its built-in web server lets you configure, control and monitor the module, its connections and I/O status from a browser, so no additional app is needed.
Two integrated 10/100 Base-TX switch ports allow modules to be daisy-chained, which reduces cabling and the number of external switches. The unit can be powered over Ethernet under IEEE 802.3af (Class 3) or from a +12 ~ +48 VDC terminal block, which helps simplify installation in DIN-rail cabinets.
For integration, the module supports OPC UA Server and Client, MQTT Client and RESTful API over HTTP or HTTPS, and these can run simultaneously. IF, THEN, ELSE logic rules and time-based schedules let you act on I/O and virtual points locally, while I/O trigger messages can be written to a CSV file or sent to a line for device tracking.
Applications
- Sending digital I/O values to cloud or field control systems for display, analysis or control strategy
- Distributed digital I/O over Ethernet with daisy-chain wiring
- Event-driven control using logic rules and schedules
