4 Channel 12V Bistable Self-locking Relay Module Button MCU Low-level Control Switch Board

Feature:
Working voltage: DC 6-24V (recommended DC 9V 12V 24V) Working current: 1 relay pulls in 37MA, 2 relays pulls in 73MA, 3 relays pulls in 110MA, 4 relays pulls in 146MA Quiescent working current: 2mA Relay load current: AC 250V/10A, DC 30V/10A Trigger mode: low level trigger Size: 65mm * 47mm * 18.5mm Weight: 56.8g
Note: This is a self-locking (bistable) relay module. When triggered once, the relay is closed (and held), and triggered again, the relay is disconnected.
Pin description:
V: Positive power supply G: The negative pole of the power supply and the ground terminal of the trigger signal; T (T1/T2/T3/T4): Trigger signal input (0.2-2 second low pulse). NO: Relay normally open port COM: Relay common port NC: Relay normally closed port
Instructions:
When power is applied, the relay is disconnected. Click the trigger port (T1/T2/T3/T4 port) the relay to pull in (and hold), click the relay again to disconnect, and so on.
