## Long description

The QOLTEC 50990 is a DIN-rail mounted WiFi relay engineered for integration with electricity metering systems and for remote circuit switching. This single-channel device supports switching currents up to 63A, enabling remote control of loads and automated switching based on meter signals or scheduled commands. Designed for residential and light commercial installations, the unit simplifies centralized control and load management while fitting standard DIN-rail distribution enclosures.
Advantages
The DIN-rail design allows compact installation within distribution panels and simplifies wiring in existing electrical cabinets. Built-in WiFi connectivity enables remote control and monitoring without additional gateway hardware in many setups. A 63A switching rating supports higher current loads than typical signal relays, making it suitable for controlling heaters, pumps, and distribution lines. Integration capability with electricity meters provides options for automated switching tied to metering events or energy management systems.
