Latching, Sequence and Impulse Relays – Application Data
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.

303 Series
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.
SECTION 7
385
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.

Alternating Relay – Application Data
712 Alternating Relay In many industrial pumping applications, two identical pumps are used for the same job. A standby unit is available in case the first pump fails. However, a completely idle pump might deteriorate and provide no safety margin. Alternating relays prevent this by assuring that both pumps get equal run time.
The Model 712 Series Alternating Relay is designed for duplex pumping systems where it is desirable to equalize pump run time. The solid state alternating circuit drives an internal electromechanical relay. A continuous power source and control switch is required. The control switch (float, pressure or other isolated contact) is connected as shown in the respective wiring diagrams. Each time the control switch is opened the output contacts will change status. Indicator lights on the case show the internal relay status. Setting the top toggle switch to the “center position” alternates the load; while setting the switch to “Load 1” or “Load 2” will lock the relay in the respected position, preventing alternation. The alternating relay approach isn’t limited to pumping applications. The control switches could be thermostats or pressure switches, and the loads could be fans or compressors.

The 711 Impulse Sequencing relay is an alternating relay used for load sharing or toggling ON/OFF of the load. Unidirectional momentary pulses cause the contacts to transfer from one side to the other. There is no need to redirect the polarity of the input in order to change and maintain states.

The Class 303 relay has been designed for 30 Amp loads by using 0.250” quick connect terminals and other proven materials used by Magnecraft power relays. Contact gaps are 2 millimeters wide to meet most standards for creepage and clearance. Its magnetic latching mechanism keeps the contact in the last set position until commanded to change by means of a separate redirected signal. The optional magnetic blowout allows for high voltage DC switching applications.

385 Mechanical Latching Relay/DPDT to 6PDT, 15 Amp Rating
0.187” Quick Connect Terminals
Switch Up to 6 Poles
The 385 relay is a mechanically latched, electrically reset relay. It can be furnished with two, four or six sets of double throw contacts. The molded, plastic dust cover snaps onto a standard DIN rail as well as incorporating mounting slots for panel mounting. The 385 does not have a dominant coil. If both coils are energized at the same time, all of the normally open contacts close and all normally closed contacts open. If one coil, (Coil A) is de-energized, then the contacts on the opposite side (Coil B) will not transition until coil power is restored to the first coil (A).
