Applications:
BRT-V490 Electronic Delay-off Timer Module can be used together with a traditional mechanical switch for automatically turning off various loads such as fans and lights. It is perfect for saving energy and bringing convenience and safety to our daily life and work. It has wide applications at various locations such as kitchen, hotels, washing room, storage room, etc
Typical application scenes include:
1. Exhaust Fan delay-off control: When using BRT-V490 in kitchen or washroom, the user can set the delay time according to the ventilation need for the site so that the power is automatically turned off after the odor or moisture is cleared out.
2. Lighting: When lighting is controlled by a traditional mechanical switch, sometimes there is a safety concern because the light is always immediately turned off. With BRT-V490 installed behind a traditional mechanical switch, the user can always exit an area with peace of mind because of the delay-off feature.
Wiring Diagram and Installation Guide:
As shown in Fig. 1, BRT-V490 Electronic Delay-off Timer Module only requires two wires for installation. Its two lead wires connect to ACL and load respectively
Hot wire (Lin): Coming in from the power line ACL with 220V; and
Load wire (Lout): Going out to the load and then ACN.
The two screw blocks in the middle are for connecting to a mechanical switch.
