W&T connects Interfaces for TCP/IP, Ethernet, RS-232, RS-485, USB, 20mA, glass and plastic fiber optic cable, http, SNMP, OPC, Modbus TCP, I/O digital, I/O analog, ISA, PCI Data sheet: Switch remotely... With the Web-IO 4.0 230V Relay 1xNO, 1xCO 230V switching signals can be controlled via TCP/IP Ethernet. There are numerous Web and network services available for switching up to 16A with the two integrated relays - even directly from the browser or from a smart phone. Using protocols such as MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things. Properties Switching signals: • 2 switching outputs: o 1 x potential-free normally open contact for 230V mains o 1 x potential-free changeover contact for 230V mains o Switching currents up to max. 16A Connectivity: • Intuitive Web interface for simpler operation o Select between German or English o Switching the outputs directly from the Web interface o Adaptation for smartphone o HTTP and HTTPS • Current Industry 4.0 protocols: o REST and MQTT support o AMQP on request • Box-to-Box o Pass switching signals over the network 1:1 • Alarm and reporting functions: o Email for alarm sending or as status report o SNMP polling / alarm traps o Switching your outputs in alarm situations o Switching the outputs on another Web-IO o HTTP requests for controlling third-party devices o Up to 12 actions can be configured • Dynamic integration into other Web sites: Direct access to the contacts via HTTP requests, AJAX and JavaScript • Additional software interfaces for incorporating into your systems/databases: o OPC o Modbus TCP o Syslog o TCP and UDP sockets, client and server o FTP (data logging) • Internal clock o Time synchronization via time server calibration o Battery-backed device clock • Possible applications: o Cross-location switching o House and building automation o Light, gate and cabinet control o More uses can be foundhere. Power supply: • External powe
