Users should thoroughly review the technical data before selecting a product part
number. It is recommended that user also seek out the pertinent approvals files of
the agencies/laboratories and review them to ensure the product meets the
requirements for a given application.
Input Data @ 25°C
Tim ing Mode
Voltage:(±10%): 12 VAC/VDC, 24VAC/VDC, 120 VAC/VDC.
Pow er Requirem ent: 4W, with rated load.
Interval.
Transient Protection: Non-repetitive transients of the following magni-
tudes will not cause spurious operation of affect function and accuracy.
Tim ing Specifications
Tim ing Ranges: 0.5 to 10 / 3 to 60 sec.; 3 to 60 min.
Tim ing Adjustm ent: External resistor or potentiometer. An external
resistance of 1 megohm is required to obtain the
maximum time for all ranges. To determine the actual
resistance needed to obtain the required time delay,
use the following formula:
