6NO30 Amperite time delay

[gerrittube]

Hi,

I use an Amperite 6NO30 time delay tube to switch a relay (230 Volt coil) in order to switch 230 Volt with higher current. When the Amperite’s 30 seconds have passed, the contacts make contact and I notice the relay rattles shortly before contact is 100%. Small sparks are visible between the contacgts. The reason is that the actual contact is made quite slowly. I’m now trying to rectify the 230 Volt AC for the relay, with a small capacitor, to get the relay switching better/faster.

Any other suggestions for improvement?

Regards, Gerrit

Mine have done that, too, albeit using it to drive a 12V relay. I put a resistor in series with the relay coil and that quenched most of it, but if you don't want any bounce, use it to drive a transistor.
