Web-IO 4.0 Digital 4x Relay Out
Potential-free switching
With the Web-IO 4.0 up to four relay outputs can be controlled via TCP/IP Ethernet. Three of the outputs can operate as potential-free normally open (NO). An additional output works as a potential-free changeover contact (CO). Numerous web and network services are available to control the switching outputs and to report or log changes - also directly in the browser. Using protocols such as OPC UA, 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:
- 4 switching outputs
- 3x potential-free contacts as normally open contacts (NO)
- 1x potential-free contact as changeover (CO)
- Switching voltage up to 48V
(110V, 230V via coupling relays) - Switching current max. 2A at 24V, 0.5A at 48 V
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:
- Box-to-Box
- Alarm and reporting functions:
