- µLAN network master controller
- Manages up to 512 sensing points
- RS485 Modbus RTU slave device
- Compact and robust design
E7718 controller operates as 1-wire master device, performing µLAN network analysis and regularly polling for data from 1-wire sensors from multiple sub-networks without conflict.
The instrument implements dynamic register assignment for sensors data, allowing to build very flexible and complex 1-wire digital sensor networks with multi-level µLAN topologies. A system involving tens of branches and sub-branches and hundreds of sensors may be easily implemented, provided that the total length of the path, active at any moment, does not exceed 100 m.
E7718 acts also as RS485 Modbus RTU slave device, storing and providing measurement data for an automation system.
The controller is fully weather and dust protected and complies with ATEX requirements for Zone 20 and Zone 21 installations in grain silos. The innovative design provides robustness and extremely fast and easy installation.
