Miniature Electropneumatic

Timing Relay

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/laboratories and review them to ensure the

product meets the requirements for a given application.

Design Features

• High Repeat Accuracy over voltage and temperature extremes

• Hermetically sealed units are designed for high shock and vibration

applications

• Instant recycling – easy linear adjustment

• Exclusive Dial Head adjustment – no needle valves

• Delay ranges from milliseconds to 3 minutes

• DPDT contacts

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 addition-

al +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 vertical 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 adjustable timing. Circular-path Dial

Head principle replaces traditional needle valve.

Snap-action switch assembly

provides sustained contact pressure during

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 assures permanent alignment

of all operating members, the key to this unit's long trouble-free operation.

Code

Operation

Series 2112 (On-Delay) -

Applying rated voltage to the

solenoid coil starts the preset time delay. At the end of the

delay period 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.) re-

cycle the unit. It will then provide another full delay period

on re-energization.

Series 2122 (Off-Delay) -

Applying rated voltage to the

coil for at least 75 msec. (for accurate timing) will instanta-

neously 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.

capacitive load should not have inrush currents that exceed five times normal

operating load.

Ambient Temperature Range:

Weight:

Maximum, any unit - 17 ozs.

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).

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

readjustment, the external knob model with calibrated dial is recommended.

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 adjustment. Hermetically sealed models provide a slotted

adjusting screw under the cap nut on the top cover.
