【Excellent Design】433 MHz RF wireless relay remote control switch. Stable and reliable performance with high receiving sensitivity (> 97dBm). Radio frequency signal transmission. The strong signal can pass through walls, floors, doors, panels, and so on. It can be controlled from up to 30 meters away in open areas. You can remotely operate each machine connected to the relay receiver via the remote control. 【Easy to Use】Extremely easy to set up and reset. This is a programmable remote control kit. There are 4 operating modes (momentary/toggle/latched/delay mode) that can be programmed. You can easily program it yourself according to your needs. The product's operating mode is adjustable. This item is already configured in latched mode. 【More Flexibility】This receiver uses a high-quality 5A relay with a lifespan of over 100,000 cycles, making it more durable and stable. The wireless relay has three terminals (normally open, common, and normally closed). It features potential-free contact relays with a passive output and dry contacts. The receiver has a wide voltage range of 100V~250V, so it works well with 220V/230V/240V systems. 【Multiplayer Control】One receiver can store approximately 20 transmitters, allowing you to share them with family and friends. The chip uses the EV1527 learning code, a secure technology system. The remote control has a long lifespan. A screw terminal on the back of the transmitter allows for battery replacement after disassembly. The battery is 2 CR2016 (included) or 1 CR2032. 【Wide Application】The products can be used in homes, farms, factories, offices, laboratories, supermarkets, etc. You can remotely control any device connected to the relay receiver via the remote control, such as garage door openers, electric locks, electromagnetic gates, lamps, lighting, ventilation devices, water pumps, signal transmission, and DIY remote control switches.
