About what is dry contact and how to wire it

This is a passive dry‑contact relay module.The receiver has three relay terminals: COM, NO and NC.

As a characteristic of dry‑contact design, these contacts will NOT output any voltage, even after the receiver is powered up.They work just like an ordinary mechanical switch.

To activate your load, you need a separate external power supply for the load (this power supply feeds the load, not the receiver), and wire COM with NO or NC to form a complete closed circuit so external current can pass through.

Recommended wiring logic:

1. Route one side of your load power supply to the COM terminal
2. Connect the NO terminal to one wire of your load
3. Link the remaining wire of your load back to the other side of the external power supply to finish the full loop

How it works:

• Remote OFF state: COM and NO stay open. No current flows, and the load remains off.
• Remote ON state: COM and NO close. Current passes through the completed circuit, turning your load ON.

Troubleshooting

Case 1: Remote no response / relay never clicks

•The remote and receiver are not paired. Complete pairing following the user manual.

Case 2: Relay clicks, but the load still does not run

•Incomplete circuit, missing load power supply, or missing COM jumper.

About Working Modes-- Pick The Right One Before Pairing Momentary Pulse Mode

Press the remote button , the relay connects, release the remote button , the relay dis-connects.

For Example,

Relay stays ON only while holding the button; turns off once you release.

Momentary mode can be applied to electric door locks!

Toggle(Use Single Key)

Press once the remote button, the relay connects , press the remote button again, the relay dis-connects

For Example,

Press ON once to activate, press ON again to deactivate.

Latched (Interlock) – Recommended

Press the remote button ON, the relay connects, press the remote button OFF, the relay dis-connect.

For Example,

Two‑button independent control. Best choice if you need separate ON/OFF keys.

Latched mode can be applied to on/off car batteries!

Timed Delay Mode (5/10/15/20 Seconds)

Press the remote button , the output terminal of the receiver will be powered on for a certain time (5s/10s/15s/20s), and the output terminal of the receiver will be powered off.

For Example,

Press ON to activate relay, it automatically powers off after preset time.

Working Mode Settings

1.Reset : Press the learning button on the module 8 times continuously, and the light flashes seven times and then goes out.

2.Momentary Mode:Press Module learning button 1 time, the indicator light is always on, then press the remote control button, the indicator light flashes 3 times and then turns off , then the learning is successful; If the code is not successful , the indicator lights out of the learning state after 15 seconds .

3.Toggle Mode:Press the Module Learning button 2 times, the indicator light always turns on; then press the remote control button, the indicator lights flicker three times and then off, then the learning is successful; if the code has not been successful, the indicator lamp goes out of the study state after 15 seconds.

4.Latched Mode :Press the receiver button 3 times, the receiver indicator light is always on, the receiver enters the code matching state, and then press the remote control button, the receiver indicator light flashes and then stays on, then press another button on the remote control, after the code is successful, the indicator light goes out.

5.Delay Mode : Press a certain number of times (4 times correspond to 5s/ 5 times correspond to 10s/ 6 times correspond to 15s/ 7 times correspond to 20s) to press the receiver button, the receiver indicator light is always on, the receiver enters the code matching state, then press the key of the remote controller, and the indicator light will go out after the code matching is successful.

Important Note

Pair the remote and receiver only once! It will save the pairing forever — even if you turn off the power, you don’t need to pair again.

Q: Why the OFF button can’t turn my device off?

A: If you want separate ON & OFF control, clear codes and re‑pair under Latched mode.

Q: What is the difference between Toggle and Latched mode?

A: Latched mode has independent ON and OFF keys.

Toggle mode is single‑key toggle control, OFF button is inactive.

• 433 Mhz universal wireless remote control switch: input voltage DC 5v-60V, working mode is superheterodyne.
• Transmission distance: about 50~100m (open space), if the transmission distance is not ideal, the antenna inside the receiver box can be pulled outside through the round hole of the box, which will be more conducive to reception.Support remote control type: EV1527 learning code. Supports up to 20 remote controllers (if the remote controller is lost, buy one to pair with the PCB board.)
• PCB size: 47 x 26 x 18 mm (L,W,H), output terminals: NO , NC , COM.
• It supports remote and wireless control of your car battery power, garage doors, electronic doors, appliances and other remote control devices, appliances, motorcycle alarms, car sunroofs, heating systems, and more. Bring you a brand new remote control experience, please don\'t miss it.
• EASY TO USE: There are 4 function modes: Momentary, Toggle，Latched and Delay, please refer to the details page below for pairing.
• You can configure momentary mode for access control; You can configure latched mode for turning on/off car battery power.
