Packing list:

 

1 pcs1 ChannelDC 12V magnetic latching(keep) relay Module








Description:

 

Working voltage: DC 12V(8-18V)
Working current: 60MA(Provide current only when switching states)
Standby current: 20uA(ORzero power consumption standby)
Load current : AC 250V/10A, DC 30V/10A
Trigger mode: Low pulse trigger
Size: 48mm * 17mm  * 17.5mm (L * W * H),  Small size
Weight: 12.5g

Module interface:
1. V: Positive power supply (VCC)
2. G: Negative power supply (GND)
3. R : Reset(Relay OFF)
4. S : Set(Relay ON)

Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays

This is a latching(keep) relay module,Trigger S port , the relay pull (and holds);Trigger R port, the relay releases (and holds)
The trigger duration is 0.5-2 seconds, it is recommended not to exceed 1 minute.

Question:
What's a latching relay?

Answer:
It is a relay that is set (ON) or reset (OFF) by the input of a pulse voltage. Even after the input voltage is interrupted, this relay maintains its set or reset condition until it receives the next inverting input. It is also called a keep relay.

 

 

Typical applications:

Automotive electronics

Industrial equipment

Motor LED PLC
Camera PTZ CCTV
UPS Uninterruptible power supply

Smart Home

Emergency lighting

MCU development board

Toy car

If you follow the wiring method of Application 2, you can achieve zero power consumption standby




Note:
The power supply cannot be reversed, otherwise it will burn out the transistor (S8050 J3Y)
But don't worry, replace the S8050 (J3Y) transistor can be used normally.
