Control four compatible circuits with SONOFF 4CHPROR3 over Wi-Fi and the eWeLink app. It provides four channels with dry contacts and multiple operating modes so you can choose the control method suited to your wiring.
Switch between independent operation, interlock and timed Inching operation. Inching lets you set a channel to turn off after a specified duration, as in the example below.
Control compatible circuits through four channels, after designing each circuit’s wiring for its voltage, current and load type. A dry contact is for control, not a power supply for the connected device.
| Specification | Details |
|---|---|
| Model | 4CHPROR3 |
| Channels | 4 |
| Unit power supply | 100–240 V AC / 50–60 Hz |
| Advertised maximum current | 10 A per channel / 40 A total |
| Connectivity | Wi-Fi 2.4 GHz |
When: A channel configured in Inching mode is turned on.
Action: Turn it off automatically after the set duration.
The advertised limit is 10 A per channel and 40 A total, and the suitability of the load type must be verified. The controlled circuit’s wiring must be designed for its requirements; do not rely on the terminal shape alone.
The DC supply range differs between the product images and the manufacturer’s manual. Do not rely on a general figure before matching the supplied unit’s label and manual with a specialist electrician.
When you want to turn on a channel for a set period and then turn it off automatically, after setting the duration and testing the load. Do not rely on it as a safety timer or with a load that needs continuous operation.
These specifications apply only to 4CHPROR3; model 4CHR3 differs in its power supply and load limits.
