NewTrend · DIN-rail eWeLink WiFi control
Product overview
The WF-Y02 is a compact DIN-rail WiFi controller for eWeLink app control. It uses an AC 230 V, 50/60 Hz supply and a marked 230 V / 2 A control output. Use it for a suitable control load or with a compatible modular contactor to switch the main circuit.

Remote control and timing
Use the eWeLink app to switch the controlled circuit on or off. Scheduled and countdown timers support switching at a selected time or after a selected interval. A front button provides setting and local manual on/off control, with separate ON/OFF and signal indications. The wireless interface uses 2.4 GHz b/g/n WiFi and supports STA, AP and STA+AP modes.
Connections and contactor operation
The side circuit diagram identifies L and N supply connections, the S1–S2 normally open external-switch input, and the A1–A2 contactor-control connection. Match the contactor control circuit to the controller output and follow the terminal markings on the supplied components.
The controller output remains limited to its marked 230 V / 2 A rating. When a separate contactor switches a larger main-circuit load, select that contactor for the actual load current and utilisation category. The contactor is not included with this controller.
Dimensions and installation
The housing measures 81 mm high, 18 mm wide and 66 mm deep and mounts on a standard 35 mm DIN rail. The normal operating range is −5°C to +40°C; the stated working-temperature limits are −35°C to +70°C. Isolate the supply before wiring or servicing.
Typical applications
- Scheduled lighting and building-control circuits.
- Remote operation of a compatible modular contactor.
- Small control loads within the marked output rating.
