Introduzzjoni
The DieseRC EW-4CH is a versatile 4-channel WiFi smart switch relay module designed for remote control and automation of various electrical devices. It offers stable and reliable performance with high reception sensitivity via 2.4 GHz WiFi. This module allows you to control devices from anywhere using the eWelink APP and integrates with voice assistants like Amazon Alexa and Google Home. It supports both inching and self-locking operating modes, providing flexibility for different applications.
The module features four independent relays with potential-free (dry) contacts, each rated for 10A. It can be powered by DC 5V (via USB) or DC 7V-48V (via terminal block), making it compatible with a wide range of power sources and applications.

Informazzjoni dwar is-Sigurtà
- Ensure all power is disconnected before installation or wiring to prevent electric shock.
- This device operates with electrical currents. Improper installation or use can be dangerous.
- Do not exceed the maximum current rating of 10A per relay.
- Kun żgur li l-konnessjonijiet kollha jkollhom iżolazzjoni xierqa.
- Operate the device within its specified voltage range (DC 5V or DC 7V-48V).
- Żomm l-apparat 'il bogħod mill-ilma, umdità, u temperaturi estremi.
- Jekk m'intix ċert dwar xi proċeduri tal-wajers, ikkonsulta elettriċista kwalifikat.
Setup
1. Installazzjoni Fiżika u Wajers
The EW-4CH module is compact (65x48x17 mm) and can be easily hidden in most electrical boxes or junction boxes. It offers flexible power input options and passive output relays.

- Input ta' Enerġija: The module can be powered in two ways:
- Via Micro USB: DC 5V/0.5A.
- Via Terminal Block: DC 7V-48V/0.5A.
- Konnessjonijiet tar-relay: Each of the four relays has three terminals:
- LE (Normalment Miftuħ): The circuit is open when the relay is off, and closes when the relay is activated.
- COM (Komuni): The common terminal for the relay.
- NC (Normalment Magħluq): The circuit is closed when the relay is off, and opens when the relay is activated.
Figure 3: Power input options: DC 7V-48V via terminal or DC 5V via USB.

3. Tqabbil tal-Apparat
- Power on the EW-4CH module.
- Open the eWelink APP and tap the '+' icon to add a device.
- Follow the in-app instructions to put the device into pairing mode (usually by pressing and holding the pairing button on the module until the WiFi indicator light blinks).
- Connect the device to your 2.4 GHz WiFi network.
Modi Operattivi
The EW-4CH supports two main operating modes: Inching (Momentary) and Self-locking (Toggle).
- Inching Mode: The relay activates for a set duration (e.g., 0.5 to 3600 seconds) and then automatically deactivates. This is suitable for applications like garage door openers or pulse-triggered devices.
- Modalità li tissakkar waħedha: The relay toggles its state with each activation. One press turns it on, another press turns it off. This is suitable for traditional on/off control of lights or appliances.
You can configure these modes within the eWelink APP for each relay independently.
