PN-150BSR Slow Release Biased Relay
General Description
The PN-150BSR relay is a slow release biased relay
that remains in the energized position approximately 1
second after control energy is removed. This feature
is used to bridge the transfer time of the controlling
relay contacts to prevent loss of information. A typical
example is the bridging of the changeover time of a
PN-150BD relay from normal to reverse (or viceversa). For longer delay time, refer to the PN-259BSR
relay in RSE-4F4 and PN-259SRA relay in RSE-4F5.
Contacts are low-voltage silver to silver-impregnated
front and silver to silver back.

General Features of ASTS USA PN-Series Electro-Mechanical Vital Relays
ASTS USA vital and non-vital plug-in relays serve a
multitude of functions in both railroad and transit
control circuit applications. These time-proven relays
are space-saving, easily installed or removed and can
be handled in the field without disturbing coil or
contact wiring.
In addition to production of PN-series electromechanical relays at the same high standards, ASTS
USA also provides high-quality remanufacturing
services for these relays so that they can be returned to
service in like-new condition. Refer to the
“Remanufacturing Services” section of this catalog or
call 1-800-652-7276 for additional information.
Other types of contact material for special application are
described with the particular relay. Standard contacts are
factory-adjusted to standard minimum opening and conform
to AREMA (AAR) requirements.
All vital plug-in relays incorporate a transparent molded
cover over the relay contacts and armature structure. The
cover is sealed to the frame with a gasket that assures a
tight, dust-proof and moisture-proof seal.
Contact Designations
Front and back contacts of plug-in relays are designated “F”
and “B”, respectively. The dependent contacts are denoted
FB, while the independent contacts are denoted “F” or “B”
alone.

Testing
Meets or exceeds applicable AREMA (AAR)
requirements
Many ASTS USA vital relays are provided a front testing
capability. The front testing facility is in series with the coil
control circuit to permit deenergization of the relay while it is
in its service mounting, without disturbing the relay or
wiring. Testing may also be accomplished through the rear
of the relay mounting base without opening a contact or coil
circuit. Refer to RSE-4S1 for special tools utilized in
maintaining ASTS USA plug-in relays.

High Quality Design and Assembly
Latch
All components of ASTS USA plug-in relays are constructed
according to rigid quality control standards and are
thoroughly tested before shipment. Coils are encapsulated
for protection against mechanical damage and moisture.
Magnetic circuits are constructed of non-aging materials.
The air gap is not disturbed when the coil is removed or the
contact springs adjusted. Those relays with an adjustable
magnetic shunt may be adjusted for degree of magnetic
hold-down force without changing the contact adjustment or
the hold-down pole-piece position.
A spring-operated latch holds each plug-in relay securely to
its mounting base. The latch is released by pressing a
button on the front of the relay.
Contact fingers and springs utilize a simple, reliable design
and are heat treated to assure uniformity of material and
contact stability. The heavy contact fingers extend through
the base to serve as plug connectors. Heel contacts are
actuated by operating arms pivoted to the armature. Contact
surfaces have sufficient wiping action to be self-cleaning.
“Standard” contact materials include fine silver heels and
backs, and silver-impregnated carbon (S.I.C.) fronts with a
typical capacity of 4A @ 30 Vdc or 175 Vac. “Heavy Duty”
(H.D.)” contact materials also include fine silver heels and
backs and silver-impregnated carbon (S.I.C.) fronts with a
typical capacity of 15A @30 Vdc or 30 Vac.
RSE-4F1, p. 2
Indexing
All plug-in relays are equipped with indexing pins to prevent
insertion of an incorrect relay into the mounting base. Each
relay is accompanied by an indexing plate that is applied to
the base at the initial installation.
System Voltage
This voltage, which is listed in the relay ordering tabulation
specifications, is prescribed for relays in locally energized
circuits. Higher voltage may be used, if required, up to 10
watts power dissipation.
