Signal relay system
Did you know?
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 transceivers which combine transmitter and receiver in one unit. The relay contacts are designed not to refl… WebFigure 5: When a train enters the block (right), the leading wheelset short circuits the current, which causes the relay to de-energise and drop the contact so that the signal lamp supply …
