ProductName:DC 12V 10A Magnetic Latching Relay Module Zero Power Hold Switch Bistable Self-locking Board for LED Motor CCTV PTZ
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/10ATrigger mode: Low pulse triggerSize: 48mm * 17mm * 17.5mm (L * W * H), Small sizeWeight: 12.5gModule 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 interface2. COM: Common Interface RelaysThis 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 PLCCamera PTZ CCTVUPS Uninterruptible power supply
Smart Home
Emergency lighting
MCU development board
Toy carIf 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.
