DIN-rail WiFi relay QOLTEC 50990, single-channel, 63A switching for electricity metering and remote control

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.

Key specifications

• Mounting: DIN-rail (standard rail profile)
• Channels: single-channel relay output
• Switching capacity: up to 63 A
• Connectivity: WiFi for remote control and integration
• Application: designed for integration with electricity meters and load management

How to use

Install the QOLTEC 50990 on a standard DIN-rail inside the distribution enclosure and connect the relay contacts to the load circuit according to local electrical codes. Connect the device to mains power and configure WiFi using the manufacturer's setup method to enable remote control. Integrate the relay with an electricity meter or control system as required for automated switching, ensuring all connections and protective devices (breakers, fuses) are correctly rated for the intended 63A load.

Recommendations

Ensure installation is performed by a qualified electrician and verify compatibility with the target electricity meter and the protection elements in the distribution board. Use the relay within its rated switching capacity and ambient conditions specified by the manufacturer. For reliable remote operation, place the device where WiFi signal strength is adequate or consider network improvements if remote responsiveness is critical.
