eletechsup DC 12V 10A Magnetic Latching Relay Module Zero Power Hold Switch Bistable Self-Locking Board for LED Motor CCTV PTZ (1)

Description:

Working voltage: DC 12V(8-18V)

Working current: 60MA(Provide current only when switching states)

Standby current: 20uA(OR zero 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.
