✅ Long Wireless Range — up to 100 meters in open space
✅ EV1527 Learning Code Support — compatible with supported learning-code remotes
✅ Stores Up to 20 Remotes — convenient multi-user memory capacity
✅ Multiple Working Modes — Momentary, Toggle, Latching, and Time Delay
✅ Relay Output Terminals — NO / NC / COM for switching a separate circuit
✅ Compact PCB Size — approx. 35 × 30 × 18 mm

🧠 Product Description:
This DC 12V 1-channel RF relay receiver is designed for applications where you need to remotely switch a relay output using a compatible 433MHz learning-code transmitter. It supports several control logics, including Momentary, Toggle, Latching, and preset Time Delay functions.

The module is suitable for remote switching, access control, garage or gate trigger circuits, alarm activation, lighting control, and general DIY automation projects.

Important: this board is powered by 12V DC, and the NO / NC / COM terminals are relay contacts, not a powered voltage output by themselves.

🧭 Remote Programming Control (Remote Not Included):

Clearing the Code:

  • Press the learning button on the receiver 8 times to clear all stored codes.

  • After clearing, all remotes must be paired again.

Momentary Mode:

  • Press the learning button once.

  • Press the desired button on a compatible remote to pair it.

  • In this mode, the relay stays active only while the remote button is being pressed.

Toggle Mode:

  • Press the learning button 2 times.

  • Press the desired button on a compatible remote to pair it.

  • In this mode, press once to turn the relay ON, press again to turn it OFF.

Latching Mode:

  • Press the learning button 3 times.

  • Press one remote button for ON, then press another button for OFF.

Time Delay Mode:

  • Press the learning button the required number of times based on the desired delay setting.

  • Pair the remote button after entering the selected delay mode.

  • Available delay presets: 5s / 10s / 15s

🔌 Wiring Notes:
⚠️ Power the receiver with 12V DC only
⚠️ Do not connect AC mains directly to the DC input terminals
⚠️ The COM / NO / NC terminals are relay contacts for switching an external circuit
⚠️ For motors, pumps, solenoids, or other inductive loads, using an external relay, contactor, or suppression protection is recommended
