{"title":"4 Channels RF Remote Control Module DC 5V","handle":"4-channels-rf-remote-control-module-dc-5v","url":"/products/4-channels-rf-remote-control-module-dc-5v","description":"This Elecrow 4-channel RF remote control module pairs a 433MHz wireless receiver board with a 5-button RF remote controller. Each of the four latching relays provides passive (dry contact) output, allowing you to switch mains-powered appliances or DC loads up to 10A without additional circuitry. The module can also be controlled directly by a microcontroller via its standard interface.\n\nThe self-locking (latching) mode means each relay toggles on and off with successive button presses. LED indicators (D1–D4) show the status of each relay channel, plus a power LED (D5). The included remote provides a range of 15–30 metres.\n\nKey Features\n\n\n4 Latching Relay Channels – Self-locking mode with passive (dry contact) output\n\n433MHz RF Wireless – 15–30 metre remote control range\n\nHigh-Current Relays – Rated up to 10A at 250VAC or 10A at 30VDC\n\nMicrocontroller Compatible – Standard interface for direct MCU control\n\nLED Status Indicators – D1–D4 for relay status, D5 for power\n\n5-Button Remote Included – Individual channel control plus all-off\n\n\nSpecifications\n\n\nWorking Voltage – 5–5.5V DC\n\nWorking Current – ~220mA\n\nQuiescent Current – ~6mA\n\nMax Load – 10A at 250VAC / 10A at 30VDC\n\nRF Frequency – 433MHz\n\nRemote Range – 15–30 metres\n\nRelay Mode – Self-locking (latching)\n\nModule Dimensions – 65 × 50 × 20mm\n\n\nPackage Contents\n\n1× 4-Channel RF Receiver Module\n1× 5-Button RF Wireless Remote Controller\n\n\n\nWarning: This module can switch mains voltage loads.
