The RELAY BOARD - INVERTER consists of a Double Pole Double Throw (DPDT)
12 volt DC relay with appropriate connectors. The unit serves two functions. It can
either be used with 12 volts DC power and a separate trigger line to ground or by
connecting to other DALLEE TRak-DT type products with the supplied two prong
wire harness. This board will invert the signal, when the DT is on this relay is off!
This function comes in handy when doing automation with other sensors (such as
motion sensors) on commercial layouts by allowing the system to only turn off
power when the detection device indicates that the train is in it's proper location to
turn the main power off. There are other applications as well.
RELAY contacts maximum rating is 5 amperes.
RELAY BOARD LATCH consists of a dual coil Double Pole Double
Throw (DPDT) 12 volt DC latching relay with appropriate
connectors. It will latch any momentary input and remember that
position with or without power applied to it. It can either be used
with 12 volts DC coil power or by connecting to other DALLEE
products with the supplied two prong cables. It comes with 2 two
prong wire harnesses to easily plug into multiple Trak-DT type
units. When used with the TRak-DTRL, you will have to solder 3
wires to the bottom of the TRak-DTRL and connect them to the
appropriate connections.
RELAY contacts maximum rating is 8 amperes.

RELAY BOARD-EXPANSION consists of a Double Pole Double Throw
(DPDT) 12 volt DC relay with appropriate connectors. The RELAY BOARD
serves two functions. It can either be used with 12 volts DC coil power or by
connecting to other DALLEE products to yield a 4PDT set of relay contacts. It
comes supplied a two prong cable to plug into the "expansion jack" (EXP) on
the Trak-DT or other DT type board. The Trak-DTRL (Item 566) requires the
use of one set of it's contacts in order to provide more contacts. Hence,
adding one 555 to it would yield a 3PDT set of relay contacts and not a 4PDT.
To create a 4PDT with the Trak-DTRL, use item 568.
RELAY contacts maximum rating is 5 amperes.

12VPS - Regulated 12 volt Power Supply
The 12VPS is a "regulated" 12 volt DC power supply. It is intended to power
devices such as the TRAK-DT family, OPTO-DT, and the KEEP-A-LIVE.
Failure to power these items with an appropriate regulated 12DC supply may
damage the boards. This damage is not covered under any warranty. Input to
the 12VPS should be 14-20 volts AC (16vAC typical, Item# 690). This input
power can come from the accessory terminals of most power packs or from a
separate transformer (preferred method). A DC input may also be used but
should be 16-22 volts DC. The 12VPS is "regulated" so it can supply a
consistent 12 volts DC to numerous TRAK-DT type devices regardless of
changes in load current. The 12VPS is capable of operating 10-15 TRAK-DT
type devices. Adequate input power is required for proper operation.
