Dayton 2A562 Time Delay Relay: 3-60 Secs On/Off?

AI Thread Summary
The Dayton 2A562 Time Delay Relay operates with normally open contacts, meaning it remains inactive until the set time period of 3 to 60 seconds elapses, at which point the contacts close. However, it does not meet the user's requirement of running for a specified time and then shutting off. Instead, the user is advised to consider an "on delay" relay with normally closed contacts for the desired functionality. A suggested alternative is the Dayton 1EGB3 Relay, which can perform the needed operation. The discussion clarifies that the 2A562 will not fulfill the user's intended purpose.

Can someone please tell about the Dayton 2A562 Time Delay Relay.
Does it wait 3 to 60 seconds before powering on, or does it wait 3 to 60 and then power off?
I am looking for something that will run for 3 to 60 seconds and then shut off.
thanks

did you do a google search ? there are many references

one I looked at stated it has a set of normally open contacts

Yes, but just because it says N.O. contacts that still doesn't answer the question of how the timer works-the the it's active or the time it waits before it's active...

well from my understanding it does :)

it implies that the contacts are open (N.O. = normally open) till the time period set is reached and then the contacts close

I'm assuming what you want is the following: When input power is applied the load receives power. When the time interval has elapsed the load is switched off. When input power is removed the cycle repeats.

If the above is what you want then you can use an "on delay" with normally closed contacts. I don't think the solid state relays will do this. However, this mechanical one will:

The 2A562 will not do what you want.

THANKS! I knew one must exist like that...
 
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'
I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
