High Current Electronic Relay
High Current Electronic Relay
Standard High Current Relays. Standard relays are common mid-to-high current rated relays that are 'mono stable' meaning that they stay in the switched state as long as a switching signal is applied. These relays are offered in varying packages, duty cycles and performance ratings, to match the application
Alibaba.com offers 1,726 high current relay products. About 61% of these are relays, 3% are contactors, and 1% are sensors. A wide variety of high current relay options are available to you, such as protective, general purpose, and auto.
The output pins of most logic gates can only supply a limited amount of current, typically no more than about 20 mA. As e-MOSFETs are voltage operated devices and consume no Gate current, we can use a MOSFET relay switch circuit to control high power loads. Micro-controller Relay Switch Circuit
Relays are electrically operated switches and can be broadly classified into contact (mechanical) and contactless (semiconductor) types. Photorelays are semiconductor relays made up of an LED optically coupled to a MOSFET, used mainly as signal relay replacements. Having no movable contacts, photorelays are known to have better long-term reliability over mechanical relays.
More information: High current relay. Dual high current electronic relays (100A 60VDC) This is a set of two independent very high current electronic relays. Use these when you want even higher current then the 50A relays, need higher voltage or need both of them on at the same time.
When an electronic circuit using a direct drive from a triac, the electronic circuit will not be isolated from the power circuit, and because of this, troubles due to erroneous operation and damage can develop easily. The introduction of a relay drive is the most economical and most effective solution.
Sometimes you need to switch a high current circuit rapidly. In this case you would use a switching transistor. A transistor is an electronic device that can work as a switch. It allows control of a large current by a smaller current as does a relay. Unlike a relay, however, a transistor is not mechanical, and can operate much faster than a relay.
IXYS/Littelfuse's high current MOSFET solid state relay (SSR) CPC1705 features low on-resistance and high load current capability suitable for many switching applications. ...

A relay is a form of electrical switch that is operated by electromagnet which changes over the switching when current is applied to the coil. These relays may be operated by switch circuits where the switch cannot take the high current of the electrical relay, or they may be operated by electronic circuits, etc.
It has been announced that Omron Electronic Components Business Europe has extended its popular G2RL power relay family with a new extra high capacity 23A model, for switching the heaviest current loads in home appliance, industrial and HVAC applications.
