Relays

-
               A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts.The relay takes advantage of the fact that when electricity flows through a coil, it becomes an electromagnet. The electromagnetic coil attracts a steel plate, which is attached to a switch. So the switch's motion (ON and OFF) is controlled by the current flowing to the coil, or not, respectively.

              A very useful feature of a relay is that it can be used to electrically isolate different parts of a circuit.It will allow a low voltage circuit (e.g. 5VDC) to switch the power in a high voltage circuit (e.g. 100 VAC or more).

Different Kinds Of Relays:

        Relays can be categorized according to the magnetic system and operation.The following are the types of the relays.



1. Latching Relay










2. Reed Relay













3. Polarized Relay  















4. Buchholz Relay  














5. Overload protection Relay










6. Mercury Wetted Relay







7. Machine Tool Relay 











8. Contactor Relay  













9. Solid State relay












10. Solid State Contactor Relay

Abstract:             Temperature maintenance is the prime consideration for the effective and safe handling of the patient. Mistakes regarding to it can lead to life-threatening condition for the patient. The normal body temperature of human is 37.5 deg. Celsius. The blood from blood bank is at lower temperature.It is dangerous to directly infuse cool blood in patient.
