Relay circuits Electromechanical relays may be connected together to perform logic and control functions, acting as logic elements much like digital gates (AND, OR, etc.). A very common form of schematic diagram showing the interconnection of relays to perform these functions is called a ladder di...

control systems called PLCs (Programmable Logic Controllers). In a PLC, a digital microprocessor performs the logic functions traditionally provided by electromechanical relays, with the programming for this microprocessor taking the form of a relay diagram (also called a “ladder logic” diagram). ...
A very simple example of a relay used to interpose between mismatched devices is shown in the following circuit diagram, where a delicate toggle switch is used to control a bank of high-power lights for an off-road vehicle: In this circuit, the relay performs no logic function whatsoever. ...
Define Relay racing. Relay racing synonyms, Relay racing pronunciation, Relay racing translation, English dictionary definition of Relay racing. n. A race between two or more teams, in which each team member participates in only a set part of the race an
(e.g., switching of AC and DC loads) while isolating the logic part of a circuitry and high-power signals. The combination of galvanic isolator plus power MOSFETs or IGBTs avoids damaging, e.g., microprocessor by high-voltage spikes while getting the flexibility to ...
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an ...
FIG. 5 shows a logic sequence diagram for tripping the circuit breakers on the basis of the result of operation of the protective relays and the result of decision using the four specific information; FIG. 6 is a block diagram showing the structure of one form of the decision circuit shown...
