Time Delays
THL-1 Series Products have three time delay options:
Onboard Adjustable Time Delay--complete Prod-
uct Number by adding two-digit Code from Table
at right, i.e., THL-1024U-30 is an On Delay with a
time delay range of 0.1-10 seconds.
Onboard Fixed Time Delay--replace two-digit
Code with suff x “F” followed by delay [0.1 ... 100]
followed by (S) seconds, (M) minutes or (H) hours,
i.e., THL-1024U-F5S is an On Delay with a time
delay f xed at 5 seconds.
Remote Time Delay--THL-1 Series products can
be built with two terminals for remote adjustable or
f xed time delays.

Remote Time Delay
THL-1 Series products can be built with two terminals for remote
adjustable or f 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 suff x “R1”, i.e., THL-1024U-30R1.
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 f xed time delay can be set by connecting a resistor across the
two terminals. To determine the resistor value required, use the
following equation:
T
R =
T
max
x 100,000
Example: Using time range 0.1-10 seconds, what resistor value is
required for a f xed time delay of 5 seconds:
5
R =
x 100,000
10
R = Resistance value required to obtain T
T
= Desired time delay
= Maximum time delay of range
T
max
= 50,000 ohms (50K ohms)
