Specialty Relays
AGASTAT 2100 Series, Miniature Electropneumatic Timing Relay
Operation
Series 2112
(On-Delay)
—
Applying rated volt-
age to the solenoid
coil starts the preset
time delay. At the
end of the delay pe-
riod the NC contacts break and the NO
contacts make. Contacts remain in this
position until the coil is de-energized,
when the switch instantaneously returns
to its original position. De-energizing
the coil, either during or after the delay
period, will immediately (within 25 msec.)
recycle the unit. It will then provide an-
other full delay period on re-energization.
Series 2122
(Off-Delay)
—
Applying rated volt-
age to the coil for at
least 75 msec. (for
accurate timing) will
instantaneously
transfer the switch,
breaking the NC contacts and making
the NO contacts. Contacts remain in this
position as long as the coil is energized.
The preset time delay period begins as
soon as the coil is de-energized, at the
end of which the switch returns to its
original position.
No power is
required during the timing period.
Re-energizing the coil, either during or
after the delay period, will immediately
start a new cycle with full delay period.
Repeat Accuracy
— NORMAL VERTICAL POSITION
±5% at 25°C; ±7% at 85°C; ±8% at -55°C.
The average time between -55°C and 85°C will be within ±20% of the average @
25°C with a proportionally reduced effect at lesser extremes.
In extremely short delay settings an additional 8 msec. variation may result on AC
models due to "half cycle" alternating current effect.
Setting Tolerance
— Factory time setting, when specified, subject to additional
+5% tolerance.
Position Sensitivity
—
HORIZONTAL POSITION — Approximately 5% increase from the initial time in the
vertical position.
INVERTED POSITION — Approximately 10% increase from the initial time in the ver-
tical position.
Reset Time
— 2112 Series: 25 msec.; 2122 Series: 75 msec.
Relay Release Time
— 25 msec. (2112 Series)
Relay Operate Time
— 75 msec. (2122 Series)

Design & Construction
Sealed patented timing head
—
circulates air under controlled pressure
through a variable orifice to provide ad-
justable timing. Circular-path Dial Head
principle replaces traditional needle valve.
Snap-action switch assembly
—
provides sustained contact pressure dur-
ing timing cycles. Specially designed
over center mechanism assures flutter-free
load transfer after extended delay periods.
Precision-wound solenoid
assembly
— supplies the basic motive
force when the control circuit is closed.
These assemblies are mounted in a rigid
self-supporting framework within a steel
enclosure. This rugged construction as-
sures permanent alignment of all operat-
ing members, the key to this unit's long
trouble-free operation.
Transients
— Insensitive to transients of ±1500 VAC for 10 milliseconds
Dielectric
— 1000V RMS @ 60Hz between non-connected terminals.

Operating Mode
—
2112
— On-delay (delay on pull-in);
2122
— Off-delay (delay on drop-out)
Timing Adjustment
— All standard
models offer easy linear adjustment over
one of nine timing ranges listed below.
For applications requiring frequent read-
justment, the external knob model is rec-
ommended. For tamper-proof
installation or where readjustment is
infrequent, the internal key model may
be preferred. This model requires
removal of the cover plate for timing ad-
justment. Hermetically sealed models
provide a slotted adjusting screw under
the cap nut on the top cover.

Mounting/Terminals
— Chassis mounting tabs, octal plugs and external (-4) or
internal (-5) adjustment. Panel mounting back plate, internal adjustment, and solder
hook terminals (-9).
Users should thoroughly review the
technical data before selecting a product
part number. It is recommended that
users also seek out the pertinent
approvals files of the agencies/laborato-
ries and review them to ensure the prod-
uct meets the requirements for a given
application.
