Trying to salvage a few of the mechanical relays from the Bridgeport under rehap.

No problem, pretty straightforward.

But have noticed that almost every relay has a component between the first of the common points and the first NO points.

It's marked:

RC Unit
630 vdc, 250 vdc (or thereabouts)
.1 mfd 100 ohms

Looks like two separate components with amber colored epoxy or similar cast around them.

Any idea why these were there?

Thanks

Tom
