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.

Type Voltage Voltage Voltage

AC 24 20 28

120 105 130

DC 12 11 13

24 20 32

Note: DC voltage must be filtered (5% p-p ripple max. at nom. voltage).

AC models will operate on 50 or 60 Hz.

Contact Data @ 25°C

Arrangements: 2 Form C (DPDT).

Material: Silver-cadmium oxide alloy.

Rating: 10A @ 30VDC or 277VAC, resistive; 1/2 HP @ 250VAC;

1/3 HP @ 120VAC.

Expected Mechanical Life: 10 million operations.

Expected Electrical Life: 100,000 operations, min., at rated load.

Initial Dielectric Strength

Between Open Contacts: 500V rms, 60 Hz.

Between All Other Conductors: 500V rms, 60 Hz.

Input Data @ 25°C

Voltage: 24 & 120VAC and 12 & 24VDC.

Power Requirement: AC Types: Typically less than 3 VA.

DC Types: Typically less than 3 W.

Transient Protection: Yes.

Reverse Voltage Protection: Yes.

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.
