123Smart relay 12V 120A

123SmartRelay is a dual relay module:

The 123SmartRelay is a dual relay module with extremely low self-power consumption. It can be used to switch high currents or even small signals. The design ensures long operation, even on very small batteries. It is a perfect companion with the 123SmartBMS when it is necessary for the BMS to be able to switch a larger current or voltage, for example a charger or an inverter.  Just connect the battery pack + and – to the module (to power the microcontroller) and a wire from the signal relay on the OUT board to the 123SmartRelay to switch the relay on/off like a normal relay.

An integrated microcontroller ensures reliable operation in harsh environments, combined with very low power consumption. Two LEDs display the current state of each relay. One flash means the relay is off, two flashes indicate the relay is on. It’s as simple as that.
