PN-250CG SS Plug-In Solid-State Code Transmitter Relay
For decades, electromechanical code transmitters
have been used to generate the pulses of coded
track circuits. While these transmitters are
reliable performers, their precise, somewhat
complex mechanisms require periodic inspection
and maintenance. ASTS USA has developed a
more cost-effective, yet equally reliable
alternative. The PN-250CG SS is a solid-state
code transmitter option for equivalent ASTS USA
electro-mechanical encoders.
General Description
In electromagnetic code transmitters, an electromagnetic circuit sustains the motion of a pendulum to
generate a pulsed signal, or code, which is
transmitted through the rails. The pendulum
alternately opens and closes a set of contacts at rates
of 50, 75, 120, 180, 276, and 420 times per minute
(codes per minute or CPM). The code rates depend
on the pendulum’s natural period of oscillation. The
PN-250CG SS coder electronically duplicates this
operation.
The ASTS USA PN-250CG SS is a solid-state code
transmitter that provides a solid-state option for ASTS
USA electromechanical coders. The PN-250CG SS
replaces the PN-250TR relay. This new code
transmitter is available in versions for either driving
traditional code following relays (using low voltage
contacts) or for directly switching 110 Vac (using high
voltage contacts) at any selected code rate applied
directly to the rail.
CE Compliance Kit and Relays
PN-250CG relays N40105623 through N40105633
are equipped with electronic components to meet
conducted and radiated immunity requirements in
accordance with EMC Directive 89/336/EEC. Other
relays in this series (see Ordering Tabulation) can be
retrofitted with a “CE Compliance Kit” to likewise meet
this specification. Components include a Tranzorb
and a Ferrite connected across the 12 Vdc power
input to the relay, and a CE compliance label. If
planning to retrofit an existing PC-250CG relay with
these components, request ASTS USA Service
Manual SM-8567 and contact your ASTS USA
Account Executive.

maintenance relays
Direct plug-in connection to existing racks
No rewiring of existing circuits
Kit available for CE compliance (conducted and
radiated immunity)
Application
Different types of contacts are provided for varying
applications with broad classifications of low and high
voltage ratings. The contacts identified as “DC” are
used to drive a code-following relay and are suitable
to switch either AC or DC. The contacts identified as
“AC” are suitable to directly code 110 Vac and apply it
to the rail. In order to ensure that units of different
code rates or contact ratings are not inter-changed,
an indexing plate is used to match a set of holes to a
set of pins on the plug-in base.
The PN-250CG SS has been designed to fit in the
same rack space as an existing mechanical coder.
Additionally all of the contact positions are identical
and the same indexing configuration has been
retained. This means absolutely no rewiring. Simply
remove the old relay and plug in the solid-state
replacement.
