6-4
RMS (Root Mean Square) Effective DC
value of sinewave voltage or current. The
effective value is .707 times the peak volt-
age or peak current measured.
Series Circuit Loads connected end to
end across a voltage source.
Set Point The point at which a controller
will perform a function. The setpoint can
be either factory fixed or user adjustable
as in a temperature controller or a timer.
Setting Accuracy The degree of accu-
racy (resolution) to which a controller set-
point can be adjusted.
Shunt A low-resistance connection
between two points in an electric circuit
that forms another path for a large portion
of the current.
SPDT (Single Pole Double Throw)
A type of contact configuration which
consists of a Common contact, Normally
Open contact, and Normally Closed con-
tact. In relay nomenclature, the states of
the contacts are given with the relay coil
unenergized.
Snubber Network Typically, a series con-
nection of a resistor and capacitor applied
across an output device (especially solid
state) to minimize voltage spikes due to
line transients or load switching. It is used
to help prevent unwanted switching of
solid state devices and arcing of mechani-
cal contacts.
Specified Delay Time The advertised
time, design print specified time, or set
time of the delay function.
Steady State The condition of a device
after power has been initially applied for
a certain period, or when its electrical
parameters are allowed to stabilize. This
condition is reflected in parameters such
as current flow, output voltage, and/or
temperature.
Storage Temperature The range of
ambient temperatures in which a control-
ler is designed to be stored, in order to
assure operation within its specifications.
May be stated in Fahrenheit or Celsius.
Termination The point at which electrical
devices are connected to field wiring of
either inputs or outputs. Typical types of
termination are: Quick connect terminals,
screw terminals, flying leads, etc.
GLOSSARY
Time Diagram A logic function drawing
used to relate the output operation of a
particular controller with regard to its input
parameters over a given period of time.
Tolerance The permissible deviation from
a specified value of an electrical param-
eter. Normally stated as a percentage of a
nominal value.
Transient A momentary occurrence of a
particular phenomenon.
Transient Voltage Voltage spikes of
short duration which occur in electrical
circuits that exceed the normal designed
operating levels. Two main types of volt-
age transient wave forms are generally
used by the industry to define the typi-
cal transients found in the field. They are
defined in the IEEE C62.41 standard
IEEE Recommended Practice on Surge
Voltages in Low Voltage AC Power
Circuits. Transient surges considered in
this section do not exceed one-half period
of the applied AC line frequency. Also, the
magnitude of the crest voltage and cur-
rent are designated as a peak open circuit
voltage of 6 kV and a peak short circuit
current of 3 kA. Of the two, the one which
simulates lightning transients is the com-
bination 8/20 S current and 1.25/50 S
voltage wave form. The simulation of
transients generated by switching large
capacitive or inductive loads is represent-
ed by a 0.5 S –100 kHz ring wave.

Volt The basic unit electromotive force or
potential difference.
Voltage The difference in electrical poten-
tial, or electromotive force between the
terminals of a source of electricity. It is
usually measure in volts.
Voltage Drop See On State Voltage.
Watt The basic unit of power.
