Power overrun alarm

The active power threshold can be set, and the alarm state is set when the measured active power exceeds the set threshold.

Communication Interface

TTL interface

Power supply

The single-phase power frequency grid power supply is supplied to the main circuit through the RC capacitor, and the TTL output communication interface is isolated from the main circuit optocoupler and is a passive output. An external 5V power supply is required for communication.

Note

The TTL interface of this module is a passive interface. It must be externally supplied with 5V power supply. That is, all four ports must be connected (5V, RX, TX, GND) during communication, otherwise communication cannot be performed.

Operating temperature
