Product information "U-7552M OPC UA I/O Module, 8-ch DI/DO with 2-port Ethernet Switch"
U-7552M is an OPC UA I/O module that brings eight digital inputs and eight digital outputs onto an Ethernet network. Its built-in two-port switch lets you pass the network through the module in a daisy chain, which reduces cabling and the number of switches needed in a panel.
Communication options cover OPC UA Server and Client, MQTT Client and a RESTful API over HTTP or HTTPS. These can run at the same time, so I/O values can be sent to a cloud platform or a field control system while the device is also reachable through the API. Local logic uses IF, THEN, ELSE rules, and scheduled execution allows rules to run at set times.
The module accepts power over Ethernet to IEEE 802.3af Class 3, or from a +12 ~ +48 VDC terminal block. Configuration, control and I/O monitoring are handled through the built-in web interface, with no additional application required. It is rated for -25 °C ~ +75 °C operation and is mounted on DIN-rail.
Applications
- Sending digital I/O status to cloud systems or field control systems for display, analysis or control strategy
- I/O trigger message logging to CSV file or line for device tracking
