[Answer] Component of a relay crossword clue

• Component of a relay Where radio transmitters and receivers share one antenna, often a coaxial relay is used as a TR (transmit-receive) relay, which switches the antenna from the receiver to the transmitter. This protects the receiver from the high power of the transmitter. Such relays are often used in transceiverswhich combine transmitter and receiver in one unit. The relay contacts are designed not to reflect any radio frequency power back toward the source, and to provide very high isolation between receiver and transmitter term…A is an of lines, or rungs, in which each line or rung must have continuity to enable the output device. A typical circuit consists of a number of rungs, with each rung controlling an output. This output is controlled by a …In utility and industrial electric power transmission and distribution systems, a digital protective is a computer-based system with software-based protection algorithms for the detection of electrical faults. Such are also termed as microprocessor type protective . They are functional replacements for electro-mechanical protective and may include many protection functions in one unit, as …A solid-state (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. SSRs consist of a sensor which responds to an appropriate input (control signal), a solid-state electronic switching device which switches power to the load circuitry, and a coupling mechanism to enable the control signal to activate this ...
  
  failures. Every time the contacts of an electromechanical or contactor are opened or closed, there is a certain amount of contact wear. An electric arc occurs between the contact points (electrodes) both during the transition from closed to open (break) or from open to closed (make).. A , sometimes called a mercury displacement relay, or, mercury contactor, is a relay that uses the liquid metal mercury in an insulated sealed container as the switching element. Mercury-wetted relay. A
