Item # 505
TIMER-1
Oscillating on / off Timer
The TIMER-1 provides an on/off power sequence of
items with equal durations of time. The time can be set
from approximately 1 to 90 seconds. You can either have
the item that you want to turn on and off start in the "ON"
state or "OFF" state. Besides using it as a simple on/off
switch, it is also possible to operate a DC switch motor. A
DC switch motor could be used to operate motion items
on your layout. Other time ranges are available on
special order. Seperate power of 14-18 volts AC is
required. The relay output handles 5 amperes.
Item # 506
TIMER-2
Dual Oscillating on / off Timer
The TIMER-2 provides two independent timers on one
board. The specifications are the same for each timer (2
on this unit) as item #505, Timer-1. Since the TIMER-2
contains two independent timers and output's you can do
different events with each of them. Other time ranges are
available on special order. Seperate power of 14-18 volts
AC is required. The relay output can handle up to 5
amperes.

OPTO-DTR
Infra-red Optical Detection - optically sensed via reflection
OPTO-DTR3 (#1553)
sensor end measures 0.48" x 0.2"
The Opto-DTR's are set for detection up to 1 foot away from the sensor. Angling the sensor helps when reading cars passing
in front of the sensor. The long sense distance allows for hiding the sensor in all kinds of places. Unlike other IR sensors,
these are also insensitive to most ambient light interference.
One sensor is included with the Opto-DTR1 while the Opto-DTR3 is equipped with 3. The Opto-DTR3 can have each sensor
individually turned on/off to allow for different configurations. Both units have an LED to assist with alignment and have
adjustable timing to keep the 5 ampere, DPDT, output relay engaged longer than the detection exists.
They do require 12 volt regulated DC to power the electronics. This is achieved using Dallee item #369. One #369 can
power up to 12 detection boards.
For advanced uses and applications refer to the information provided on our web site at: USE & ADVANCED APPLICATION
SUGGESTIONS. Also be aware that the OPTO-DT's can be substituted for the TRAK-DT's and Trak-DTT's in the
suggestions provided there.
