Remote Time Delay

THS-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., THS-10242­30R1.

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:

R =

T
