Welcome to our store! 1. [Learnable] This switch is designed to learn multiple remote controls, allowing each remote to control all buttons on the switch. This means one remote can control multiple switches, or multiple remotes can control one switch. 2. [Easy to Use] The controller outputs dry contact signals and can be switched on. It's designed for ease of use and flexible combination, allowing you to combine it as needed. 3. [Operating Voltage] The relay remote control can be used with either resistance-capacitance voltage resistance or power module voltage resistance. Its operating voltage range is DC12V-36V. The maximum load it can handle is a 10A relay. For resistive loads, it can handle less than 8A, and for inductive loads, it can handle less than 3A. 4. [With Battery] The remote control switch comes with 4 CR2016 (75mAh) button batteries. It operates at a receiving frequency of 433MHz and can achieve momentary, latching, and interlock functions by shorting the pads. 5. [Application Scope] Relay remote control switches are mainly used in various industries such as lighting, electric doors and windows, lifting equipment, elevator control, and security.
