National Controls Corporation-Time Delay Relays (Model:Q1F Series)

Operating Logic: Upon application of input voltage, the delay starts. At the end of the time delay, the load is energized. Reset is accomplished by removing input voltage.

• 100% functionally tested
• Time delays to 10 hours standard
• Solid state digital timing
• 20:1 maximum to minimum timing ratio
• Compact size
• Low cost
• Superior transient protection
• Flame-retardant and solvent-resistant polyester thermoplastic housing

Note:

1) The load may be located on either side of the line;

2) Remote potentiometer leads should be shielded when running close to other wires;

3) The minimum time setting on external resistor-adjustable time delay relays is obtained by shorting together the external resistor terminals of the relay;

4) The maximum time setting within tolerance limits is obtained by using a 1 megohm resistor;

5) Timing values between the minimum and maximum limits are linear with resistance within 10%;

6) Recommend 1/4 W minimum resistor be used.
