Control switching signals via TCP/IP Ethernet with Web-IO 4.0 230V Relay - W&T
April 1, 2021
Switch remotely...
Using the 57838 Web-IO 4.0 230V Relay 4xNO, 4xCO you can control 230V switching signals via TCP/IP Ethernet. There are numerous Web and network services available for switching up to 6A with the eight integrated relays - even directly from the browser or from a smart phone.
Using protocols such as MQTT ( Message Queue Telemetry Transport )and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.
Switching signals:
- 8 switching outputs:
- 4 x potential-free normally open contacts for 230V mains
- 4 x potential-free changeover contacts for 230V mains
- Switching currents up to max. 6A
Connectivity:
- Intuitive Web interface for simpler operation
- Select between German or English
- Switching the outputs directly from the Web interface
- Adaptation for smartphone
- HTTP and HTTPS
- Current Industry 4.0 protocols:
- REST and MQTT support
- AMQP on request
- Box-to-Box
- Pass switching signals over the network 1:1
- Alarm and reporting functions:
- Email for alarm sending or as status report
- SNMP polling / alarm traps
- Switching your outputs in alarm situations
- Switching the outputs on another Web-IO
- HTTP requests for controlling third-party devices
- 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:
- OPC
- Modbus TCP
- Syslog
- TCP and UDP sockets, client and server
- FTP (data logging)
- Internal clock
- Time synchronization via time server calibration
- Battery-backed device clock
- Possible applications:
- Cross-location switching
- House and building automation
- Light, gate and cabinet control
Power supply:
- External power
- Screw terminal
- 230V AC (50Hz)
Standards & more
