AC (Alternating Current) An electric current that
reverses direction in a circuit at regular intervals.
Accuracy The variation between the specified delay
time and the Actual Time value, given in percent of
specified delay. [(Actual Time – Specified Delay Time)
/ Specified Delay Time)] x 100.
Actual Time The actual delay of a given device with
sufficient OFF time to input voltage to permit full
recovery of the timing interval. The resulting average
of a group of consecutive time delay readings (exclud-
ing the first) may be used to determine the Actual
Time. Five cycles should be considered adequate for
the determination.
Ambient Temperature Temperature of the air which
encircles an object.
Ampere (Amp) The basic unit of electric current.
Arc A luminous discharge of electric current crossing
a gap between two electrodes either through the air
or over an insulated surface. It is deleterious to elec-
tromechanical switches, limiting contact life.
Break The moment and/or location at which a series
circuit is opened and made discontinuous.
Brownout A condition in which the supply voltage is
insufficient to power the load.
Circuit A closed path followed or capable of being
followed by an electric current.
Closure The moment and/or location at which two
contacts meet to complete a circuit.
Conductor A substance or medium that conducts
heat, light, sound, or especially an electric current.
Contact Chatter (Contact Bounce) Occurs when
an electromechanical switch is in the process of mak-
ing connection in a circuit; for a brief time period,
the contacts will bounce together until they are fully
seated.
Contacts Electromechanical components that make
or break a connection between two conductors that
permit a flow of current.
Controller A regulating mechanism, as in an electric
device used to control a particular process based on
input parameters.
CSA Canadian Standards Association (Testing
Laboratory for products sold in Canada.)
Current The amount of electric charge moving in a
conductor past a specified circuit point within a given
time. The basic unit is the ampere.
Cycle A single complete execution of a periodically
repeated event or a periodically repeated sequence
of events.
De-energize To remove power from a device.
Delay To postpone an event until a later time.
Delay On Break (Off Delay) A particular type of tim-
ing function whereby the OFF event is delayed after a
start circuit is opened.
Delay on Make (Delay On Energize, On Delay) A
particular type of time function which delays the ON
event upon initial application of power to the timing
device.
Dielectric Breakdown The voltage potential at which
the insulating properties of a non-conductor will break
down and conduct current. Measured in Kilovolts.
DC (Direct Current) An electric current flowing in one
direction (constant polarity), as opposed to Alternating
Current.
DPDT (Double Pole Double Throw 2 Form C
Contacts) A type of contact configuration which con-
sists of two isolated sets of contacts operating simul-
taneously. Each contact set consists of a Common
contact, Normally Open contact, and a Normally
Closed contact. In relay nomenclature, the states of
the contacts are given with the relay coil unenergized.
Electricity A basic phenomenon in nature which
involves the movement of electrons in a medium. This
movement of electrons or electric current is considered
a source of power.
Electromotive Force (EMF) Difference in electrical
potential measured in volts.
Encapsulant A compound, typically epoxy or silicone
elastomer, used to envelop and seal components in an
electronic circuit.
Energize To apply power to a device.
External Adjustment A remotely located component
or device which is used to alter an input or output
parameter on a controller.
Factory Calibration To adjust a controller during the
manufacturing process to specific points in order to
meet the operational specifications.
Factory Fixed Fixing a particular control parameter
during the manufacturing process to make it non-
adjustable in the field.
Frequency The number of repetitions within a given
time of a complete wave form, as of common line
voltage with typical frequencies of 50 or 60 cycles per
second. See Hertz.
Full-wave Rectified AC Alternating Current changed
to Direct Current utilizing both the positive and nega-
tive portions of the AC sine wave.
Ground The point of an electric circuit that is at a zero
volt potential with respect to the earth.
Guaranteed Range The range of operation of a con-
troller or controlled parameter which the manufacturer
specifies reliable consistent operation.
Half-wave Rectified AC Alternating Current changed
to Direct Current utilizing only the positive or negative
portion (not both) of the AC sine wave.
