Features Feature: 1. Multifunction: The 8 channel remote control switch outputs switching signals for eight relays, which can enable the equipment or motor to be controlled to meet the requirements of switching or on off conversion and various special control procedures. 2. Advantages: The wireless receiver module has high confidentiality, stable performance, low power consumption, stronger anti interference, and longer receiving distance. 3. Easy to Use: Using the traditional jumper cap adjustment function, the wireless signal transmitted by the remote control is received and saved by the receiving controller, which can be used together. 4. High Sensitivity: Using a single 300‑450MHz wireless (ON OFF for Keyed) receiver chip, mainly used in the field of radio frequency remote control, higher sensitivity, in the 433MHz application environment sensitivity can reach 109dBm. 5. Application: Suitable for all kinds of smart home, electronic equipment, and production equipment, road gate, rolling shutter door, security monitoring, motor, access control button, etc Specification: Item Type: Relay Remote Control Switch Material: ABS, PCB (Battery Not Included) Battery Type: 1 x 23A Battery (each remote control require 1) Input Voltage of Control Board: DC12V-DC40V Operating Frequency: 433MHz Standby Current: 5mA Receiving Sensitivity: -105dBM Working Modes: Momentary, Toggle, Interlock Output Signal: Can output 4 way switch signal or 4 way DC12V-DC40V voltage signal Encoding Method: Learning Code Modulating Method: ASK Operating Temperature: -10°C~+70°C packing list: 1 x Receiver 2 x Remote Control Package List 1 x Receiver 2 x Remote Control
