Most THR Series products can be built with two terminals for
remote adjustable or fi xed time delays. To order a product with a
remote time delay, complete the Product Number by adding the
two-digit Code from the Table shown on the appropriate product
selection page followed by the suffi x “R1”, i.e., THR-10262-30R1.
Contact Macromatic for information on limitations of remote time
delays on functions with ON & OFF timing ranges.
Adjustable Time Delay
A 100K ohm potentiometer is required to obtain the maximum
time delay for all standard ranges. To use other values of remote
potentiometers, contact Macromatic.
Fixed Time Delay
A fi xed time delay can be set by connecting a resistor across the
two terminals. To determine the resistor value required, use the
following equation:
Example: Using time range 0.1-10 seconds, what resistor value is
required for a fi xed time delay of 5 seconds:
R = Resistance value required to obtain T
T = Desired time delay
Tmax = Maximum time delay of range
x 100,000
R = T
Tmax
R = 5
10 x 100,000 = 50,000 ohms (50K ohms)

THR-3 Series Products have three time delay options (two for THR-3856U dual-time
product):
Onboard Adjustable Time Delay-after selecting the desired time range, use the
top-mounted potentiometer provided with the unit to adjust within that range (The
THR-3856U has independently selectable & adjustable ON & OFF times).
Onboard Fixed Time Delay-although these units come with an onboard
potentiometer, they can be used to replace products with fi xed time delays. After
selecting the desired time range, set the top-mounted potentiometer at the fi xed
delay required (epoxy can be applied to prevent further changes if desired).
Remote Time Delay (THR-3816U & THR-3836U only)-after selecting the
desired time range & setting up the unit for remote time delay adjustment,
connect a remote potentiometer for remote adjustability or a resistor for fi xed
time delay. Note that these products will only work with 100K, 1M or 2M remote
potentiometers or resistors.

Upon application of input voltage, the time delay relay

the output is energized. Upon removal of the trigger, the

the output is de-energized. Any application of the trigger
during the time delay will reset the time delay (t) and the
output remains energized.

Upon application of input voltage, the time delay relay
is ready to accept a trigger. When the trigger is applied,
the output is energized and the time delay (t) begins.
During the time delay (t), the trigger is ignored. At the
end of the time delay (t), the output is de-energized and
the time delay relay is ready to accept another trigger.
Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. To be-
gin with, time delay relays are simply control relays with a time delay built in. Their purpose is to control an event based on time.
Typically, time delay relays are initiated or triggered by one of two methods, depending on the function:
application of input voltage
application of a trigger
These triggers can be one of two signals: a control switch (dry contact), i.e., limit switch, push button, fl oat switch, etc., or volt-
age (commonly known as a power trigger).
CAUTION: any time delay relay that is designed to be initiated with a dry contact control switch trigger could be dam-
aged if voltage is applied to the trigger switch terminals. Only products that have a “power trigger” should be used
with voltage as the trigger.
To help understand, some defi nitions are important:
Input Voltage - control voltage applied to the input terminals. Depending on the function, input voltage will either initiate
the unit or make it ready to initiate when a trigger is applied.
Trigger- on certain timing functions, a trigger is used to initiate the unit after input voltage has been applied. As noted
above, this trigger can either be a control switch (dry contact switch) or a power trigger (voltage).
Output (Load) - every time delay relay has an output (either mechanical relay or solid state) that will open & close to
control the load. Note that the user must provide the voltage to power the load being switched by the output contacts
of the time delay relay. In all wiring diagrams, the output is shown in the normal de-energized position.
Below and on the following pages are both written and visual descriptions on how the common timing functions operate. A Tim-
ing Chart shows the relationship between Input Voltage, Trigger (if present) and Output. If you cannot fi nd a product to fi t your

Function/Code Operation Timing Chart
FLASHER
(Off First) Upon application of input voltage, the time delay (t)
begins. At the end of the time delay (t), the output is
energized and remains in that condition for the time
delay (t). At the end of the time delay (t), the output
is de-energized and the sequence repeats until input
voltage is removed.
FLASHER
(ON First) Upon application of input voltage, the output is energized
and the time delay (t) begins. At the end of the time
delay (t), the output is de-energized and remains in that
condition for the time delay (t). At the end of the time de-
lay (t), the output is energized and the sequence repeats
until input voltage is removed.
ON/OFF DELAY Upon application of input voltage, the time delay relay
is ready to accept a trigger. When the trigger is applied,
the time delay (t1) begins. At the end of the time delay
(t1), the output is energized. When the trigger is re-
moved, the output contacts remain energized for the time
delay (t2). At the end of the time delay (t2), the output is
de-energized & the time delay relay is ready to accept
another trigger. If the trigger is removed during time
delay period (t1), the output will remain de-energized and
time delay (t1) will reset. If the trigger is removed during
time delay period (t2), the output will remain energized
and the time delay (t2) will reset.
SINGLE SHOT
F ALLING EDGE
Upon application of input voltage, the time delay relay
is ready to accept a trigger. When the trigger is applied,
the output remains de-energized. Upon removal of the
trigger, the output is energized and the time delay (t)
begins. At the end of the time delay (t), the output is
de-energized unless the trigger is removed and re-ap-
plied prior to time out (before time delay (t) elapses).
Continuous cycling of the trigger at a rate faster than the
time delay (t) will cause the output to remain energized
indefi nitely .
WATCHDOG
Retriggerable
Single Shot
Upon application of input voltage, the time delay relay
is ready to accept a trigger. When the trigger is applied,
the output is energized and the time delay (t) begins. At
the end of the time delay (t), the output is de-energized
unless the trigger is removed and re-applied prior to time
out (before time delay (t) elapses). Continuous cycling
of the trigger at a rate faster than the time delay (t) will
cause the output to remain energized indefi nitely.
TRIGGERED
ON DELAY
Upon application of input voltage, the time delay relay
is ready to accept a trigger. When the trigger is applied,
the time delay (t) begins. At the end of the time delay (t),
the output is energized and remains in that condition as
long as either the trigger is applied or the input voltage
remains. If the trigger is removed during the time delay
(t), the output remains de-energized & the time delay (t)
is reset.
