AGASTAT GP/ML/TR Series, 10 Amp Control Relay,
Non-latching, Latching & Timing Versions
GP/ML/TR Design Features
Among the advances
AGASTAT control relays
offer over existing designs is
a unique contact operating
mechanism. An articulated
arm assembly amplifies the
movement of the solenoid
core, allowing the use of a
short stroke coil to produce
an extremely wide contact
gap. The long support
arms used in conventional
relays are eliminated. Both
current capacity and shock/
vibration tolerance are
greatly increased, as well
as life expectancy.
Design/Construction
AGASTAT control relays are
operated by a moving core
electromagnet whose main
gap is at the center of the
coil.
The coil provides a low
mean turn length and also
assists heat dissipation.
Since the maximum travel of
the electromagnet does not
provide optimum contacts
movement, an ingenious
amplifying device has been
designed.
This consists of a W-shaped
mechanism, shown in
Figure 1. When the center
of the W is moved vertically
the lower extremities move
closer to each other as can
be seen in the illustration.
The center of the W mecha-
nism is connected to the
moving core of the electro-
magnet and the two lower
points are connected to the
moving contacts.
Two of these mechanisms
are placed side-by-side to
actuate the four contacts
sets of the relay. These
arms act as return springs
for their corresponding
contacts.
The mechanical amplification
of the motion of the electro-
magnet permits a greater
distance between the con-
tacts, while the high effi-
ciency of the electromagnet
provides a nominal contact
force in excess of 100
grams on the normally open
contacts.
All the contacts are posi-
tioned well away from the
cover and are well ventilated
and separated from each
other by insulating walls.
The absence of metal-to-
metal friction, the symmetri-
cal design of the contact
arrangement and the lack
of heavy impacts provides
a mechanical life of
100,000,000 operations.
For use in AC circuits, the
relay is supplied with a
built-in rectification circuit,
thus retaining the high DC
efficiency of the electro-
magnet. The current peak
on energizing is also elimi-
nated and consequently
the relay can operate with
a resistance in series (e.g.
for high voltages or for
drop-out by shorting the
coil). The use of the rectifi-
cation circuit offers still
other advantages. The
same model can operated
at frequencies ranging from
40 to 400 cycles. Operation
of the relay is possible even
with a low AC voltage.
The plastic dust cover has
two windows to facilitate
cooling and also to allow
direct mounting of the relay.

TR Design/Construction
Couples an advanced
electromechanical design
with a field-proven solid-
state timing network, an
adaptation of the circuit
used in the AGASTAT
premium grade SSC Timer.
This unique circuit also
eliminates the need for sup-
plementary temperature-
compensation components,
affording unusual stability
over a realistically broad
operating temperature
range. It also provides
transient protection and
protection against prema-
ture switching of the output
contacts due to power
interruption during timing.
