Relays are used in a variety of applications to switch a signal from one form to another. The 11 pin latching relay is a unique type of relay that is used in circuits where the power supply is limited. This type of relay uses a pulse to switch the position of the contacts and then latches in place. In this article, we will discuss the wiring diagram and schematic of the 11 pin latching relay in detail.
Introduction
A latching relay is a type of relay that uses two coils to latch in either an on or off position. When a pulse is applied to the relay, the position of the contacts changes and then remains in that position until another pulse is applied. The 11 pin latching relay is a popular choice for applications where low power is required, due to its low power consumption and ability to maintain a state without power.
What is an 11 Pin Latching Relay?
As the name suggests, the 11 pin latching relay has 11 pins. It has two coils, one for switching the contacts and the other for latching the contacts in place. The two coils are polarized and have different colors, making it easy to identify them.
The relay contains two sets of contacts, which can be normally open, normally closed, or changeover contacts. The contacts are rated for a specific voltage and current, and the relay must be selected based on the requirements of the circuit in which it will be used.
Wiring Diagram
The wiring diagram for the 11 pin latching relay is shown in Figure 1. The relay has 11 pins, which are numbered 1 through 11. Pins 1, 2, 3, and 4 are for the coil that switches the contacts, while pins 5 through 11 are for the coil that latches the contacts in place.
Figure 1: Wiring Diagram of the 11 Pin Latching Relay.
As shown in the wiring diagram, pins 1 and 3 are connected to the power supply, while pins 2 and 4 are connected to the switching device. When a pulse is applied to the switching device, the contacts of the relay will change position. Pins 9 and 10 are used to monitor the position of the contacts and can be connected to an indicator or other device to show the state of the contacts.
Pins 5 and 6 are connected to the latching coil, while pins 7 and 8 are connected to the power supply. When the contacts of the relay are in the desired position, a pulse is applied to pins 5 and 6 to latch the contacts in place. The relay will remain in this position until another pulse is applied to pins 5 and 6 to change the position of the contacts.
