Chapter 16, Test 7 Flashcards
A(n) __________ is a solid-state control device that controls an industrial process or machine.
PLC
A(n) __________ is a timer that maintains its current accumulated time value when its control input is interrupted or removed.
retentive timer
A(n) _________ is a timer that does not maintain its current accumulated time value when its control input is interrupted or removed.
non-retentive timer
A(n) __________ is a device in which the contacts change position immediately and remain changed for the set period of time after the timer has received power.
One shot (interval) timer
A(n) __________ is a timer that operates with equal ON and OFF time periods.
symmetrical recycle timer
A(n) __________ is a timer that is controlled by an external transistor from a separately powered electronic circuit.
transistor-controlled timer
A(n) __________ is a timer controlled by an external sensor in which the timer supplies the power required to operate the sensor.
sensor-controlled timer
A(n) __________ is a device used to count inputs and provide an output (contacts) after the preset count value is reached.
up counter
A(n) __________ is a counting device that keeps track of the total number of inputs and displays the counted value.
counter
A(n) __________ is a device used to count inputs from two different inputs.
up/down counter
__________ diagrams are the actual diagrams which match the logic of manufactured product line diagrams.
wiring
__________ timers are used in applications that require a load to remain energized even after the input control has been removed.
off-delay
A(n) __________ circuit provides a very accurate timing function at the most economical cost.
