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.
Timing Mode
One Shot (Latching Interval).
Timing Specifications
Timing Ranges: 0.5 to 10 / 3 to 60 sec.; 0.5 to 10 / 3 to 60 min.
Timing Adjustment: 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:
( ) ^{Rt =}
T_req - T_min
T_max - T_min
x 1,000,000 ohms
Accuracy: Repeat Accuracy: ± 1%
Overall Accuracy: ± 2% at R = 1 megohm.
Reset Time: 50 ms, max.
Output Switch Data
Arrangement: Solid state 1 Form A (SPST-NO).
Rating: 1A, inductive, at nominal operating voltage.
Expected Electrical Life: 100,000,000 operations at rated load.
Initial Dielectric Strength
Between Terminals and Mounting: 3,000VAC rms.
Between Input and Output: 1,500VAC rms.

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
Rt _formula:
( ) ^{Rt =}
T_req - T_min
T_max - T_min
x 1,000,000 ohms
