Feature: 1. Applicable to household electric lights, motors, electric switch doors, rolling doors, retractable doors, etc. 2. Stable performance, small size, high receiving sensitivity. 3. Wireless intelligent remote control system for multiple using scenarios. 4. With 2 relays, the equipment to be controlled can reach the forward and reverse rotation of the motor, or the on/off switching of the switch and various special control procedures. The product has the characteristics of stable performance, small size and high receiving sensitivity. 5. Mainly used in electric door, window, lifting equipment, gateway, lifter, industrial control and security industry, etc., it can be combined with remote control to form a complete wireless intelligent remote control system. It is widely used, especially for wired. Door and window control systems and anti-theft alarms enable wired to wireless system switching. 6. The receiver is powered by 12V. The default is an independent relay semaphore output (ie, no voltage output). The output terminals are normally open, normally closed, and common (no voltage). Specification: Item Type:Remote Control System Working voltage: DC12V Static working current: ≤6mA Working temperature: –20°C to +60°C Receive sensitivity: 3-105dBm Working frequency: 433MHz Size:68 x 48 x 16.8mm / 2.68 x 1.89 x 0.66in This switch can be applied to the following two occasions. 1. With 12V voltage output, this only needs to draw a positive line from the input terminal to the common terminal and then share the input negative line to directly control the 12V device! 2. Directly connect the normally open end and the common end of the output side to other voltage circuits to control its opening and closing! (Recommended control voltage range: 3V-250V current range: 0.1A-10A resistive load) Remote Control Quantity:1/3/5(Optional) Package List: 1 x Module3 x Remote Control Note: The power supply is recommended to use a DC regulated power supply or battery of 500mA or more. The receiving board can withstand up to 10A per channel and can directly drive DC/AC loads. Each relay has a set of normally open (normally closed) contacts. In order to extend the service life of the receiving board, it is not recommended to control the high-power load. When controlling 220V, it is recommended to control the maximum maximum of 500W (inductive). When controlling 12V, the maximum control is recommended to be 50W (inductive).
