Product information "U-7561M OPC UA I/O Module, 11-ch Power Relay with 2-port Ethernet Switch"
U-7561M is a networked I/O module that switches 11 power relay channels and reports their status over OPC UA, MQTT and RESTful API. Its built-in dual-port Ethernet switch lets you pass the network through the module in a daisy-chain, which reduces cabling and the need for separate switch ports.
The module can receive power from a PoE-enabled network (IEEE 802.3af, Class 3) or from a +12 ~ +48 VDC terminal block. Each relay is Form A (SPST N.O.) rated 5 A @ 250 VAC/24 VDC for resistive loads, with programmable power-on and safe values.
Configuration, control and monitoring are handled through a built-in web interface in a browser. Logic rules (IF, THEN, ELSE), scheduled actions and I/O trigger messages can run locally, and OPC UA, MQTT and RESTful API can be used at the same time.
Applications
- Remote switching of loads over an Ethernet network
- Passing I/O values to cloud or field control systems for display, analysis or control strategy
