Feature: 1. [Learnable] The switch can learn multiple remote controls, and all buttons of each remote control can be learned, one remote control can control multiple switches, or multiple remote controls can control one switch. 2. [Easy to Use] This controller can output dry contact signal and output live. The operation is simple, the matching is flexible, and it can be combined arbitrarily. 3. [Working Voltage] Relay remote control can choose resistance capacitance anti pressure or power module anti pressure, DC12V‑36V working voltage, maximum load: 10A relay, resistive load less than 8A, inductive load less than 3A. 4. [With Battery] The remote control switch has 4 CR2016 (75mAh) button batteries, 433MHz receiver frequency, and can short circuit the pads to achieve momentary, latching, interlock. 5. [Scope of Application] The relay remote control switch is mainly used in the fields of lamps, electric doors, window, lifting equipment, elevator control and security industries.
