ILTS 115 Relays Exam [100% PASS] /verified/
ILTS 115 Relays Exam [100% PASS] /verified/ An electromechanical relay will usually have only one coil but may have any number of different contacts. *Ans* True Normally closed contacts are contacts that are closed when the coil is de-energized and open when the coil is energized. *Ans* True Control relays are used to switch large motor loads. *Ans* False The current that can be handled by the contacts of a relay is the same that required to operate the coil *Ans* False The drop out voltage of an electromechanical relay is normally higher than the pick up voltage *Ans* False Like electromechanical relays solid state relays have coils ad contacts *Ans* False Solid state relays are normally sealed units that cannot be repaired *Ans* true It is normal to measure a small voltage drop across the normally open output terminals of a solid state relay when the relay is switched on *Ans* True In an optically coupled solid state relay, the output is isolated from the input by means of a light emitting diode (LED) *Ans* True A solid state relay designed to control a DC load may use a transistor to connect the load to the line *Ans* True Zero voltage switching of AC loads increases the in-rush current *Ans*
