Counter Solid-state relay Timer Electromechanical relay 4 A solid-state relay has a shorter life and is more susceptible to contact wear-out when compared to an electromechanical relay.  True False 5 A solid-state timer can control timing functions ranging from a fraction of a second to hundreds of seconds.  True False 6 A timer can be modified to deliver more than one type of timing function. True False 7 _____________ are used in applications where functions need to be delayed or loads need to be maintained for a predetermined period of time.  Relays Timers Terminal Blocks 8 How many circuits can a single throw contact control?
