$20-30 over here for a simple delay on relay.

first off
I am presuming your using servo drives? If they are Industrial end drives often they will have brake relays built in and often they can be set up with delays, I know mine can be so may be worth investigating if yours can as it would be the simplest and most robust option.

Hey BR549, The delay relay is a great idea and i did some exploring online. I did not see anything in the $20 or $30 range. Do you know of one? I can relay the power supply itself with the 120 vac input or relay the 24 vdc output. The brake pulls less then 1 amp.

Grainger online catalog search for time delay relay. Low as $15.00

BR549, you are right. There are a couple that will work perfectly in the Grainger catalogue. For the benefit of others that may have the same problem I am going to use a Dayton #2A561. Thanks for your help.
