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 Function
On Delay – Output relay turns on at the end of a programmed time interval
which is started by applying input voltage. LED flashes when output relay
is off and is on continuously when the output relay is on. Removal of input
voltage turns off output relay. Reapplying input voltage resets the unit.
Initial Dielectric Strength
Between Output Poles: 1,500V rms, 60 Hz.
Between Input and Output: 1,500V rms, 60Hz.

Timing Adjustment: Digital adjustment via thumbwheel switches.
Tolerance: ± 0.05% ± 0.04 sec.*
Repeatability (Including first cycle of operation.): < ± .05% ± 0.04 sec.*
Reset Time (power interruption): 45 ms, typ.; 60 ms, max.
* Timing is synchronized with input voltage frequency. Accuracy is dependent on input
voltage frequency. Tolerance shows maximum variation from utility companies.
