ControlByWeb WebRelay IP relay | 1 relay + 1 input | PoE or 9–28 V DC

The ControlByWeb WebRelay (X-WR-441-E) is an IP module with one relay and one input, for example for controlling locks, lighting, pumps or bells and for remote rebooting of network devices. The relay (SPDT, 12 A) works in on/off or pulse mode, and the optically isolated input (4–26 V DC) can monitor a device, control the local relay or a relay of another module on the network. The device has a web-based control page and setup without extra software, drop-down conditional and scheduled tasks (Task Builder), e-mail notifications, logging and P2P networking with other ControlByWeb controllers (up to 32 remote modules). For integration it supports HTTP/HTTPS, XML, MQTT, Modbus TCP/IP and SNMP; the optional ControlByWeb Cloud simplifies remote access. Powered by PoE (Class 1) or 9–28 V DC.
