impulse relay

Impact relay is a kind of memory relay; Because the relay saves its previous state and reverses the state of the relay upon receiving a pulse. This relay is used in places where the consumer has to turn off or on from multiple places.

JBH brand Iranian impact relay product is offered to you with a 3-year unconditional replacement warranty.

What is an impact relay?
Impulse relays (memory relays, staircase relays or Impulse Relays) are used for staircases and places where the consumer must be turned off and on from several places. The main difference between an impact relay and a single-phase contactor is in its type of excitation.

Single-phase contactor stimulation is permanent and impulse relay stimulation is pulsed (momentary).

In a single-phase contactor, as long as the voltage is applied to the steering coil, the contactor is connected, and as soon as the voltage is removed from the coil, the contactor is disconnected; But in the impact relay, by applying voltage in the form of a pulse (momentary) to the coil, the impact relay is connected, and when the second pulse is applied to the coil, the impact relay is disconnected; Therefore, the JBH two-bridge impact relay has 2 power inputs (bridges or contacts), 2 power outputs (bridges or contacts) and 2 command inputs, each of which bridges can withstand a current of 16 amps. If the user wants a current of 16 amps or less, he must pass the phase through one bridge and the neutral through the other bridge, and if he wants a current between 16 and 32 amps single-phase, by bridging or doubling the bridges and only passing the phase through Two bridges will be able to draw current up to 32 amps.

In fact, it is 32 amps for fully ohmic loads and 8 amps for fully self-contained loads.

If you intend to buy all types of impact relays, you can place an order through the jbh website. On this site, you can get to know the types of protective relays such as glass relay, refrigerator relay, SSR electronic relay and other types and get to know their use and nature.

What is the application of impact relay?
The main application of the impact relay is to control a lighting from several points.

Staircase lighting

For an apartment staircase with a lighting line (including the total of ceiling lights) by means of an impact relay and a number of news alarm chassis (number of units), the lighting of the staircase can be controlled from several points. As soon as the user enters the apartment, he presses the first chassis and the lights turn on. When entering the residential unit, press the chassis of the unit to turn off the lights. Of course, in the discussion of energy management, the use of a timer is essential.

The lighting of large multi-door halls

In large halls and sheds, one of the challenges is to control the lighting in the hall. In these halls, there are usually several doors with a large distance from each other. If the user enters through door 1 and turns on the ambient lights, and the exit time is at door 2, he has to return to door 1 to turn off the lights. While, if the impact relay is used to control the lights and a starter thumb is installed in each door and all the thumbs are parallel to each other and connected to the impact relay steering coil, this challenge is solved.

Important points that you should observe regarding the use of impact relay

If all or part of the transformer oil has been drained and we have added oil to it and put the transformer back into the circuit, it is possible that the air bubble will collect in the relay; Therefore, there is a possibility of relay alarms in the next 24 hours.
If the temperature changes quickly, there is a possibility of air bubbles inside the relay.
If the relay alarm appears, bubbles or air inside the valve should be observed; After that, ventilate; If there is no air, there is a possibility of false operation of the relay, therefore, to ensure the health of the contents, tests should be performed to measure the insulation resistance of the relay contact and the operation of the switch.
If the trans oil level is lower than the relay, the relay will operate.
If a connection is related to insulating papers, the color of the gas produced is yellow or white, and if a connection is related to oil, the color of the gas is gray and black.

Advantages of JBH double bridge impact relay

Considerable reduction of wiring in lighting projects
It has an automatic manual mode button
The small dimensions of the miniature as a result of the ease of use, along with the miniature fuses and excellent harmonics, which are very effective in the beauty of the final product.
High beauty compared to existing contactors
Very low disconnection and connection noise
Resistant to dust and as a result no noise
It has two 16 amp contacts which can be increased up to 32 amps if bridged
Has a disconnect and connect display
A lower price than other impact relays in the market
A very high number of connections due to the presence of silver in the place of disconnection and connection of contacts

In this section, we will introduce you to the wiring of the JBH two-bridge impact relay.

Command
Base A1 and A2 are for feeding the coil to apply the command to the impact relay. By applying a momentary pulse of 220 V alternating current to these two pins, the user connects the impact relay; In this way, the power blades of the contactor are connected.
