Self Latching Relay Circuit

Even after the input voltage is interrupted this relay maintains its set or reset condition until it receives the next inverting input.

Self latching relay circuit.

It is a relay that is set on orreset off by the input of a pulse voltage. A latching relay is electrically set to one position and it remains latched in that position until it is electrically reset to the opposite position. We can make this circuit or logic with relay also. Relays with lower resistance coils will need larger value capacitors and smaller value resistors.

The circuit as shown has been tested with the jaycar sy4060 relay. It will work with other dpdt twin coil latching relays but the resistor and capacitor values may need to be adjusted to suit. Get it as soon as thu oct 8. What is a latching relay.

Free shipping on your first order shipped by amazon. This circuit or logic known as latching and unlatching circuit or logic. Plc ladder diagram for latching and unlatched circuit program description. It is also called a keep relay.

Here i demonstrate a circuit which is a simple asynchronous sr latch using a relay. 5 0 out of 5 stars 1. When the push to make button is pressed 12v goes across the coil energising the relay. The diagram above shows how such a relay can be used to make a latching relay circuit the circuit has two buttons one is a push to make which closes when pressed but is otherwise open and the other is a push to break which opens when pressed but is otherwise closed.

For this application we use s7 1200 plc and tia portal software for programming. There are two kinds of latching relays. Only 5 left in stock order soon. Relay latching circuit using push button we connect relay and push button as per figure.

Livisn dc 12v 10a 2 channel self latching relay module one button bistable switch one button start stop high level trigger. An electrically latched relay is a standard relay with one of its own contacts wired into its coil circuit.
