The Challenge
Wireless relay controller for long-range remote switching over distances up to several kilometers.
The Solution
Sub-GHz wireless (868MHz) for long-range penetration. Helical antenna keeps the footprint compact while maintaining good omnidirectional coverage. An alarm relay provides local fault indication, and X2 capacitors are used for AC-coupled water level sensing. Screw terminals for field connections.
Results
Reliable long-range switching deployed across multiple sites with centralized scheduling through the gateway.
