AGASTAT Solid State Time Delay Terms and Definitions
Accuracy, absolute (or calibration accuracy) - the deviation of a selected
time delay from the actual delay, measured with reference to a time standard,
under standard conditions.
Accuracy, "attainable" - the "worst case" deviation in time delay, from a
selected value, including all factors that contribute to its "error budget,"
including long-term drift, temperature drift, resolution, calibration accuracy,
line-voltage and line-frequency effects, etc.
Accuracy, overall - the maximum deviation from the average of 100 consecu-
tive time delays at any given time setting throughout the operating tempera-
ture, voltage, and frequency ranges.
Accuracy, repeat - the maximum deviation from the average of 100 consecu-
tive time delays at any given time setting and any fixed combination of
temperature and operating voltage.
Breakdown, circuit-to-case - the voltage insulation between any part of a
TDR's circuitry and the frame or any other conductive part in the structure,
including the case.
breakdown, control-to-load - the voltage insulation between control and
load circuits.
Calibration linearity - in the mechanical calibration of a TDR delay-setting
scale, the largest deviation of the actual delay-vs-rotation curve from a straight
line drawn from minimum to maximum delay.
Counting TDR - a TDR in which a stable source generates precisely timed
voltage pulses, and a digital counter registers a different voltage pattern or
code on its output terminals for each pulse counted. The counter is connected
to a digital decoder, preset to recognize a given code, which then operates the
load-switching device.
Current drain - the current drawn by the delay and switching circuits in the
TDR, not including the current drawn by the load.
delay - an interval of time generated before some planned event is caused to
occur.
Delay adjustability - the capability of setting the duration of a time delay
generated by a TDR; the
Delay range and resolution - taken together, describe the adjustability.
Delay adjustment - means of setting the duration of a time delay: pointer-
knob-and scale, thumbwheel switch, external or internal potentiometer, etc.
delay range - the span of time within which a TDR can generate time delays.
Dielectric withstand - the ability of insulating materials and spacings to
withstand specified overvoltages for a specified time without flashover or
puncture.
Electromechanical relay (EMR) - a controlled switch operated by causing
sufficient current to flow through an electromagnetic coil; the resultant
magnetic field, when strong enough, overcomes a spring force and closes and/
or opens the switch contacts.
Interface - in a TDR, one of the following: the nature of the means of adjusting
time delay; of indicating status of delay and load; of powering control and load
circuits, or of switching control and load circuits.
Isolation, control-to-load - the degree to which interaction has been pre-
vented between control and load circuits in a TDR usually expressed as the
effective impedance between them.
Leakage current - the current conducted by a solid state switching device in
an "off" state.
LED readout - a numerical display made up of light-emitting diodes (solid state
devices that glow when current is passed through them).
linearity - the regularity of calibration of a delay scale - i.e., the uniformity of the
spacing equal delay increments. In a TDR with externally controlled delay, the
constancy of the delay-to-resistance ration.
Line-frequency sensitivity - the deviation in delay, at any setting within
specifications, per hertz or percent of line-frequency change from the nominal
value, measured at specified line voltage and ambient temperature.
Line-voltage sensitivity - the deviation in delay, at any setting within
specification, per volt or percent of line-voltage change from the nominal value,
measured at specified line voltage and ambient temperature.
Load-dependent delay - the characteristic of certain TDR's in which there is
a significant change, due to internal heating, of a preset delay interval,
following a long "load-ON" period.
Dimensions are shown for
reference purposes only.
Dimensions are in inches over

specified.

Load rating - the maximum current, voltage, and frequency (if AC) of the load-
circuit energy that may be switched by a TDR, for normal life expectancy.
Load gates - solid state circuits that perform logic "switching functions."
Mode - see operating mode.
Noise - any unwanted signal impinging on a circuit or its environment.
Operate time - the longest interval between energization of an output relay
and the completion of contact transfer under any combination of operating
temperature and voltage.
Operating life - a measure of the number of operations a TDR can be expected
to perform within specifications; for TDRs with electromechanical (EMR) load-
switching means, there are two ratings - mechanical and electrical operations
at full rated load.
Operating mode - the relationship between control signal input, generation
of delay or count, and transfer of load-switching contacts.
operating voltage range - the range of voltages over which a TDR will perform
to specification. May be applied to either delay generating circuits, load-
switching circuits or both.
Peak current - the maximum short-duration load-circuit rating of the load-
switching circuit; also called "in-rush" or "surge" current.
R-C timer - an electronic time-delay relay in which the charging of a capacitor
(C) through a resistor (R) generated the delay and an electronic circuit
establishes a threshold, or critical value, for the capacitor voltage; when this
value is reached, a load-switching device is operated.
Release time - the longest time interval between de-energization of an output
relay and the complete transfer of its contacts under any combination of
operating temperature and voltage.
Resettability - the precision with which a delay adjustment, once changed,
can be reset.
Reset time - the shortest allowable interval between complete or interrupted
timing cycles without risk of delay error or malfunction.
Resolution - the precision with which delay adjustment may be set; it depends
on the type of adjustment means; for example, in a switch-settable design, the
smallest change that can be made by moving one unit in the least-significant
decade in a selector switch array.
solid-state relay (SSR) - a relay in which a semiconductor device (e.g., an SCR
or TRIAC), switches the load.
Stability, long-term - the measure of the effect of time along on the delay
generated by a TDR under specific operating conditions - e.g., the difference
in the repeat accuracy between that measured when the TDR is new, and that
measured one year later.
Stability, temperature - the effect of ambient temperature on the delay of a
TDR, expressed in terms of the percent deviation in a preset delay per degree
of temperature change from some nominal value.
TDR - time-delay relay.
Time-delay relay (TDR) - a device that upon energization or operation of a
control circuit, generates a delay, at the end of which some planned event (e.g.,
load switching, or secondary control function) is caused to occur.
Timing diagram or timing ladder - a graphic representation of two or more
sequences of events, all drawn to the same horizontal time scale, so that any
point in one sequence occurs at the same time as any point directly above or
below it in another sequence.
Timing range - the range of time intervals over which a particular TDR will
generate delays.
Transfer - the switching of a relay's contacts from one state to the other, but
in the past tense commonly used to denote the position of the contacts in the
relay's energized or "transferred" state as opposed to its de-energized or
"normal" state.
Transient protection or transient suppression - the prevention of malfunc-
tion of a TDR due to power-line transients, or the means of doing so. Usually
effective only over a stated range or up to a stated maximum transient
amplitude and duration.
Transient voltage tolerance - the largest momentary overvoltage peak that
a TDR will withstand without damage or catastrophic malfunction.
