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.

Repeat Cycle.

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:
