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
Delay on operate – Delay period begins when input voltage is applied. At
the end of the delay period, the relay will operate and will not release until
input voltage is removed. Reset occurs when input voltage is reapplied.

CL Timing Specifications
Timing Ranges: From 0.1 to 1.0 sec. through 1.2 to 120 sec.
Timing Adjustment: Fixed, external resistor and knob adjustable.
Tolerance (for AC units add ±1/2 cycle 60 Hz.):
Knob Adj. Types:–0, +20% of max. specified at high end of timing
range; min. specified, or less, at low end.
Fixed Types: ± 5%.
Res. Adj. Types: ± 10% at high end of timing range; min. specified, or
less, at low end.
Repeatability (for AC units add ±1 cycle 60 Hz.): ± 3%.
Release Time: 100 ms, typ.; 150 ms, max.
Recycle Time: 100 ms, typ.; 150 ms, max.
CU Timing Specifications
Timing Ranges: From 1.0 to 10 sec. through 1.0 to 120 sec.
Timing Adjustment: Fixed, external resistor and knob adjustable.
Tolerance (for AC units add ±1/2 cycle 60 Hz.):
Knob Adj. Types:–0, +20% of max. specified at high end of timing
range; min. specified, or less, at low end.
Fixed Types: ± 5%.
Res. Adj. Types: ± 10% at high end of timing range; min. specified, or
less, at low end.
Repeatability (for AC units add ±1 cycle 60 Hz.): ± 3%.
Release Time: 150 ms, typ.; 225 ms, max.
Recycle Time: 150 ms, typ.; 225 ms, max.
Note: On CU types the switching contact may momentarily transfer if the timing interval is
interrupted. CL types have no timing cycle interrupt transfer.
