Energy Conservation Relays

In many applications it is important for the customer to conserve electrical energy. One approach to energy conservation in

an electrical system is to use relays that do not require constant power to maintain contact closure.

“Latching relay” is a generic term that is used to describe a relay that maintains its contact position after the control power

has been removed. Latching relays allow a customer to control a circuit by simply providing a single pulse to the relay control

circuit. Latching relays are also desirable when the customer needs to have a relay that maintains its position during an

interruption of power.

There are three main types of Latching relays. Magnetic latching, Mechanical Latching and Impulse Sequencing.

Magnetic Latching Relays

Magnetic Latching relays require one pulse of coil power to move their contacts in one direction, and another, redirected pulse

to move them back. Repeated pulses from the same input have no effect. Magnetic Latching relays are useful in applications

where interrupted power should not be able to transition the contacts.

Magnetic Latching relays can have either single or dual coils. On a single coil device, the relay will operate in one direction

when power is applied with one polarity, and will reset when the polarity is reversed. On a dual coil device, when polarized

voltage is applied to the reset coil the contacts will transition. AC controlled magnetic latch relays have single coils that

employ steering diodes to differentiate between operate and reset commands.

Mechanical Latching Relays

Mechanical latching relays use a locking mechanism to hold their contacts in their last set position until commanded to change

state, usually by means of energizing a second coil. Since the relay does not rely on a magnet, the locking strength will

not degrade over time or weaken during thermal cycling. The contacts will remain locked in the directed position until the

opposing coil has been energized. Packaging machinery that places several units into a single container would be a good

example.

Impulse Relays

Impulse relays are a form of latching relay that transfers the contacts with each pulse. Many impulse relays are made up of a

magnetic latch relay and a solid state steering circuit that, upon application of power, determines which position the relay is

in and energizes the opposite coil. The contacts transfer and hold that position when power is removed. When reenergized,

the contacts transfer again and hold that position, and so on. In order to transfer the contacts, one simply provides a single

unidirectional pulse. There is no need to redirect the control pulse or reverse the polarity.

Impulse relays can be used as wear equalizers. They are well suited for applications such as turning a single device on or off

from one or more locations with a single momentary switch or push button at each station. For example, a conveyor could be

started and/or stopped from multiple locations by means of a single button at each position.
