Allows connection of up to 32 SPM-4-relay relays
You can connect 32 SPM-4 relays to one SPM-main. Each SPM-4Relay has 4 isolated channels to help you manage your devices more conveniently.
You can monitorpowerconsumption by checking the eWeLink app on your mobile phone. Easily obtain information about current, voltage, and power.
Supports a maximum current of 20A/channel
Each channel can support a maximum current of 20A without fear of being unable to operate more demanding consumers.
Enables RS-485 communication protocol
SPM-Main communicates with SPM-4 relays via RS-485, enabling multi-terminal and stable data transmission in the case of longer connections
Overload protection
When overload protection is enabled, it can protect your devices from excessive electrical current
Note: The main unit (SPM-MAIN) and 4-relay power meters must be used together. The main unit must be connected to at least one 4-channel relay to operate.
